Introduction of several common inflatable cabinet accessories:

1. The shell of the inflatable cabinet is welded with an airtight structure, which eliminates the harm of environmental factors. The compressive strength of the insulation layer of SF6 vapor is 2.2 times that of gas, so as to obtain the advantages of saving indoor space, reducing the total area of the building and obtaining excellent economic benefits.

2. Adopt metal laser welding machine skills to prevent the vapor body of the SF6 insulation layer from escaping and prevent moisture intrusion. The inflatable cabinet of this type of metal laser welding machine considers the provisions of IEC60698 and VDE0670 Part 1000 standard on the airtight working pressure management system;

3. The tightness of the vapor body has been routinely tested by the integrated leak detection machinery and equipment on each cover;

4. The actual operation required is transmitted from the outside of the inflatable cabinet to the inside, which is carried out through the metal bellows;

5. The electrical components installed in the cabinet are connected to the cable or busway through the welded waterproof sleeve;

6. The presentation of the preparation of the work of the inflatable cabinet is presented outward by the magnetic combination of the measuring box installed in the cabinet without contact;

7. In order to judge whether there is a working voltage, cast the capacitor integrated IC on the waterproof sleeve welded into the housing. The cabinet door control panel is equipped with a power socket, which can be used to measure the working voltage outside to detect whether there is a working voltage.

8. Usually weld the same kind of pressure relief machinery and equipment in the cover shell.

The following are some important inflatable cabinet accessories related to the relevant functions:

1. Integrated switch:

The integrated switch can be a combination of an isolation switch, a circuit breaker switch, and a grounding switch, or a combination of load switch and grounding switch, or a load switch, a grounding switch, and a high-voltage fuse. Choose different all-in-one switches according to user needs. Combining the individual switches together greatly reduces the volume, eliminates the interlock between switches, and has better stability;

2. Wiring sleeve:

As the contact point between the internal switch and the external power supply, the wiring sleeve requires good performance, sufficient load capacity, and ensures air tightness;

3. Dynamic seal components:

The dynamic seal assembly is also called dynamic cooperation, which is the connection part between the integrated switch and the operating structure, and the operating mechanism is operated externally, and the action is transmitted to the internal switch through the sealing assembly to achieve the operation function and ensure the sealing.

4. Explosion-proof valve:

The explosion-proof valve is a vent reserved for the gas box of the inflatable cabinet, which is sealed under normal circumstances, and the sealing material is not as solid as the inflatable cabinet airbox, when the switch fails to heat up, causing the temperature to rise, resulting in a sharp rise in the internal air pressure, if there is no pressure relief port, the entire airbox is easy to burst, and the loss is serious.

5. Operation structure:

The operating mechanism of the inflatable cabinet is also divided into manual and electric, and the electric operation structure can realize the "three remote functions", and the operating mechanism is connected with the internal switch through the dynamic seal assembly, so as to play the operation function.
