Tips for daily use of gas-filled cabinets

Daily usage tips for inflatable cabinets:

When the induction power supply board is fully or partially working, the maintenance machinery and equipment should be displayed separately from the working machinery and equipment. 2. The voltage transformer and the secondary winding resistance of the voltage transformer require reliable grounding protection.

When conducting the secondary circuit of a voltage transformer, the following safety measures should be taken.

3.1. It is strictly prohibited to separate the current control circuit;

3.2. To stabilize the short-circuit fault of the secondary electromagnetic coil of the voltage transformer, short-circuit fault plates and short paths must be used.

3.3. It is strictly prohibited to operate the control circuit and transmission line between the voltage transformer and the short-circuit fault terminal. 4. When operating the secondary circuit of a voltage transformer, the following safety measures should be taken.

4.1. Strictly avoid short-circuit faults or grounding devices.

4.2. When necessary, insulated tools and gloves should be used before operation.

4.3. When accepting temporary loads, special types of power switches and circuit breakers must be available.

4.4. To avoid reverse voltage on the secondary side, in addition to the secondary circuit breaker, the next circuit breaker should also be selected.

4.5. Before the secondary circuit is connected to the power supply or a high-voltage test is conducted, the on-duty personnel and relevant personnel should be notified, and a dedicated person should be arranged to inspect the site of the control circuit and decide that no one will operate after the operation.

4.6. When the staff are inspecting and turning off the power supply for maintenance and secondary circuits, no conversion work of the gas-filled cabinets is allowed without the consent of the staff.

5. The environment of the gas-Insulated Switchgear also has very high requirements:

5.1. This is the working environment temperature of the air filling tank. The temperature should not exceed 40 degrees Celsius, and it should not exceed minus 40 degrees Celsius. The humidity in the environment should not be too high.

5.2. Secondly, the usage height of the inflatable cabinet should not exceed 2 kilometers above sea level. If it exceeds this height, it is necessary to negotiate with the manufacturer and take appropriate measures.

5.3. When using an inflatable cabinet, the seismic intensity should not exceed 8 degrees, the horizontal acceleration should not exceed 0.4g, and the vertical acceleration should not exceed 0.2g.

5.4. The usage site must not have water droplets, frost, dew or other phenomena. It is not allowed to come into contact with flammable and explosive substances to ensure the usage effect of the gas-filled cabinet.

5.5. If you need special models of gas-filled switchgear products, be sure to communicate with our company. We will customize various models of inflatable cabinets for you to enhance the quality of our products and services.
