Chapter 206 Introduction
The railway system has clear regulations for the advance power supply time of direct power supply trains. The direct power supply trains must complete the locomotive connection 60 minutes before, and in case of special circumstances, it should not be less than 40 minutes. All units will work together within the specified time. Push the bottom of the car to the platform, and quickly assemble the electric locomotive to supply power to the passenger train compartment, so as to preheat or precool the train in time, boil the boiling water in the electric tea stove, and keep all kinds of electrical equipment in good condition. working status.

Under normal circumstances, every two months, the railway system of the whole country will make a notification, rewarding the good and punishing the bad for the information on the departure, addition and power supply time of the direct power supply trains. , together with the station dispatching department, and report separately. For the late trains that add electric locomotives, the reasons will be distinguished, and the responsible unit will be found for notification and assessment throughout the road. If the circumstances are serious, the operating responsibilities of the on-site operators and relevant leaders Personnel management responsibilities.Through this kind of continuous supervision from top to bottom, it is ensured that passenger trains can supply power in a timely manner, meet the hospitality standards of appropriate temperature and boiling water in the tea stove as soon as possible, and keep the train feeling comfortable and in the best state for passengers to ride.

However, since there are principles in everything, there will be exceptions. The Railway Corporation attaches so much importance to the power supply time of direct power supply trains, but sometimes due to objective reasons, the bottom of the train cannot be pulled up to the platform in time, pre-cooling and pre-heating, Not enough time to boil water.

Regarding the cabin temperature of air-conditioned trains, it is stipulated that the temperature in summer is between 26 and 28 degrees, and between 18 and 20 degrees in winter.Both ends in each compartment are equipped with thermometers, and the temperature controller in the air-conditioning control cabinet also has a compartment temperature display.Air-conditioned trains have temperature sensors to collect the temperature of the carriages, which are installed at both ends of each carriage. In the crew room, on the ceiling at the door of the toilet, and in the air-conditioning outlet and return grilles, the sensors measure the temperature there.

In fact, the temperature of each part of the entire compartment is slightly different, especially when the passenger is directly under the air-conditioning outlet, the temperature difference between this position and other places is more obvious.

And those passengers who have slept on the upper bunk of the sleeper often feel that the air conditioner is too cold, that is because it is too close to the air outlet of the air conditioner.Sometimes passengers on the upper berth will react strongly to the temperature and ask the conductor to increase the temperature of the air conditioner.In fact, as long as the air-conditioning compressor on the train is running, the temperature of the cool air coming out of the air-conditioning outlet is basically the same.

Adjust the air-conditioning and refrigeration device to automatically set the temperature. After the temperature sensor detects that the temperature of the return air outlet reaches the initial set value, the compressor will automatically stop working. At this time, the air-conditioning device only has the fan and the condenser. The fan continues to run, and what blows out from the air outlet of the air conditioner is the circulating air in the compartment.

When the temperature in the car gradually rises and reaches the set value again, the air conditioner compressor will restart to cool the car again.

According to regulations, under normal circumstances, the air-conditioning knob should be set to the "automatic" position, so that the thermostat will automatically adjust the operating status of the train air-conditioning device according to the set value and the actual temperature of the carriage.

The "manual" position corresponds to the "automatic" position. The "manual" position is characterized by a fast cooling speed, which is generally only used when the temperature of the cabin needs to be quickly lowered or the thermostat is damaged, and once the "manual" position is turned, special attention should be paid to observing the temperature inside the car at any time. Because the air conditioner in the train will keep on cooling all the way regardless, if the temperature inside the train is lower than 18 degrees, the compressor will continue to work, and the problem of burning out the air conditioner compressor will easily occur at this time.

The air conditioner compressor is the core component of the air conditioner. It is not only expensive, but also quite troublesome to replace.Under normal circumstances, after the train is powered on, the train crew should walk along the carriages and turn on the power supply and air conditioner one by one, so that the power load of the entire train is gradually added, otherwise it is prone to failure.

The K18 train used to have a generator car, and the crew of the generator car would usually send electricity in advance, and then they would turn on the machine for as long as possible to keep the temperature inside the car longer.

K18 has been running for about a month after the direct power supply train was replaced. Now it is the end of June and the heat is unbearable.

On this day, when the train departed, the train did not get out of the warehouse for a long time, so Liu Qun reported to the section production dispatching command center. After quickly understanding the reason, the production dispatching command center gave feedback to Liu Qun. A late train just entered the station, and it happened to occupy the line that Liu Qun and the others left the depot.Moreover, this is a long-distance train, and it is necessary to add water on the platform and replace locomotives. Such delays, Liu Qun and his car will only have 30 minutes to drive after they get on the platform.

Liu Qun quickly launched the emergency plan of "the platform at night under the train", requiring two train crew members (and one to assist the locomotive to be added) to start up separately and quickly. Set to automatic mode.

The two inspection cars are in their positions, one goes from the soft sleeper to the hard sleeper, and the other starts from the hard seat car with 8 cars.Just wait for the power to turn on the air conditioner quickly.

But Liu Qun knows that at such a time, the outside temperature reaches 35 degrees, and the temperature inside the car often reaches 37 degrees. Lower the temperature to about 15 degrees.

The emergency plan includes the train crew's handling when the temperature of the platform under the train is too high or too low at night. If it is found that the temperature inside the train is obviously not as good as the temperature of the platform, it must be explained to the passengers. Next, try to persuade passengers to wait on the platform first, and wait for the temperature in the car to return to normal before boarding.

At this time, it is necessary to consider the words of the train conductor and conductor. At this time, when force majeure is encountered, the temperature does not meet the standard. How to appease the passengers has become the top priority in the work.

The passenger transportation department of the railway is equivalent to the front shop in the "front shop and back factory", and those departments such as engineering, locomotive, electrical affairs, and power supply are equivalent to the back factory. No matter what products the back factory produces, whether there are any mistakes, the products Whether there are any defects, all need the front shop - the station and the train to explain the work to the passengers.Passengers' anger and complaints can only be made to the staff of the station car in the front store, and it is impossible to get angry with the staff of the maintenance, engineering, and electrical departments of the rear factory. Although the problem is not caused by the passenger transport personnel, and the passenger transport Personnel are also experiencing high-temperature roasting.

At this time, the electric locomotive had already waited for the turnout, and the electric locomotive was attached to the bottom of the car, and it took about 5 minutes to power on.

At the same time as the locomotive was hung up, the announcement of passenger ticket clearance at the station rang, and another 3 minutes later, sweaty passengers flocked from the ticket gate.
