How to turn off the dry transformer circuit key? Dry type transformer door jump switch

1.The dry-type transformer thermostat is not displayed Fault cause: The thermostat power supply is not connected; The fuse blows. Solution: Turn on the power supply; Replace the fuse.

If the dry transformer is closed in the tour room, it can be closed manually directly.

There are two ways to regulate the voltage of dry-type transformer: one is on-load voltage regulation, which is relatively simple, and directly adjusts its control switch. The second is non-excitation voltage regulation, dry-type transformer non-excitation voltage regulation is through the adjustment of the transformer itself, and there are two ways to arrange the connecting piece, with two rows of upper and lower rows

If excessive dust accumulation is found, it must be removed immediately to ensure air circulation. In places with large dust accumulation, dry-type transformers are cleaned at least once every six months. For dust in the ventilation ducts.

Vacuum cleaners or compressed air should be used for removal. If not removed in time, it will affect the heat dissipation of the transformer, and will also lead to the reduction of transformer insulation or even cause insulation breakdown. For example, our company's 220kV Weizhuang transformer station and 35kv station were used in a power outage test.

Using a 2500V optical Eurometer to measure the core insulation resistance of a dry-type transformer, the core insulation resistance is reduced to 3m, which is much lower than the last test data of 100m, the main reason is that the dust in the transformer ventilation duct is not cleaned, and the core insulation resistance rises to 100m after cleaning.

How to close the circuit line, it is generally to turn off the dry-type transformer, and then open some surgeries inside, and then manage.

However, there is a maximum button above the temperature control of the transformer, which can be clicked.

The phone should be turned off, the button on the machine should be turned off, and then unplugged.

It's just cheap.,How to turn off the line back key, you should be able to turn it off in the settings.。

I think it should have a manual, and you can follow the instructions to know how to turn it off.

The operation of the dry pressure conversion cycle progressive operation is as fierce as a tiger.

The dry transformer circuit button should be turned off, there should be a big button on the top of the temperature control box, and it can be turned off by clicking the button.

Just said that the transformer of this bear home words can be turned off, depending on its function switching.

It is an auxiliary protection and can be selected for tripping. Prevent inadvertent entry into the live interval.

How about the switch? Ask questions with trouble and be clear!

Dry-type transformers do not have voltage regulating switches (sectional switches), while oil-immersed transformers have voltage regulating switches;

The dry-type transformer voltage adjustment is carried out by switching the connecting lugs on the side of the transformer.

Not all transformers have voltage regulating switches, transformers without voltage regulating switches are often when there is a power outage, change the position of the connecting piece on the transformer body, ABC three phases have such a connecting piece, open the transformer cabinet door. There may be a runner to regulate the pressure.

Not all of them are used, you have a voltage regulating terminal.

This is to monitor the temperature of the transformer, the temperature of the three coil windings of the ABC, the temperature of the core of the transformer, several temperature cycle display switching, if the temperature is too high, it will alarm, and even jump upstream high voltage switch.

1. Three-phase temperature patrol display: every 2 seconds, the three-phase temperature value of A, B, and C is displayed, and the ranking of the temperature value of each phase is automatically displayed.

2. A variety of display methods: the maximum value mode can automatically display the maximum temperature value and phase sequence; Any phase temperature can be quickly switched and locked; The maximum temperature value memory display shows the maximum value that has been reached in any phase before the current moment.

3. Fan start and stop control: When the maximum temperature value is greater than or lower than the fan start and stop set value, the fan control contact is closed or disconnected, and there is a status indicator indication.

4. Over-temperature alarm: When the maximum temperature value is greater than the over-temperature alarm set value, the sound and light alarm will be carried out, and the alarm output contact will be closed at the same time for the user to connect to the secondary alarm circuit.

5. Over-temperature tripping: When the maximum temperature value is greater than the over-temperature set value, the tripping alarm light will be on, and the tripping output contact will be closed for the user to connect to the tripping control circuit.

6. Fault alarm: When the PT100 sensor and lead wire in the transformer A, B and C phases are broken or short-circuited, the fault light will be on, and the alarm output contact will be closed for the user to connect to the fault handling circuit.

See instruction manual.

Generally, the alarm temperature of F-class dry-type transformers is usually set at 100 degrees Celsius, and the trip temperature is generally set at 130 degrees Celsius (I have seen those set at 150 degrees Celsius). Setting at 80 degrees is clearly too low. This is generally the temperature at which the fan is turned off, and the fan is generally started at 100 degrees.

Many thermostats have set up passwords, and the password must be correct to adjust, I don't know what brand of temperature control you use?

Don't turn it off, the fan is activated due to the high temperature of the transformer, which is automatically controlled by the temperature control.

There are two ways to put it off, 1. Adjust the starting temperature of the temperature control and 2. Remove the power cord of the temperature control.

There's usually a manual button on the panel, and it's good to press it again.
