The load switch on the column has the capacity of carrying and breaking the rated current, but cannot break the short-circuit current. It is mainly used for line segmentation and fault isolation. (1) Gas-producing load switch. The gas-generating load switch uses the slit composed of solid gas-gen...

Oil-immersed transformers occupy a large market share in my country, but the oil leakage problem of transformers is a big problem and hidden danger in the power industry, especially the oil leakage of transformer high-voltage bushings is a relatively common problem in the power industry, and For ...

First of all, it is necessary to understand the use environment. The high-voltage load switch is an electrical appliance whose function is between the high-voltage circuit breaker and the high-voltage isolation switch. The high-voltage load switch is often used in series with the high-voltage fus...

The high-voltage load switch fully adopts the arc-extinguishing advantages of the vacuum switch tube and the corresponding operating mechanism. Since the high-voltage load switch does not have the ability to break short-circuit current, it is relatively simple in structure and suitable for occasi...

Many people do not understand the isolation switch and load switch, two kinds of switch is considered universal, can be replaced, but some occasions can not be replaced, Kesu electromechanical xiaobian tell you what is the difference between isolation switch and load switch. The isolation switch ...

The precautions for the use of oil-immersed test transformers are as follows: 1. Connect the working circuit according to the required test. The shell of the oil-immersed test transformer and the shell of the control box (table) must be grounded reliably. The X-end (high-voltage tail) of the high...

Oil-immersed transformers use oil as the main insulating means of the transformer and rely on oil as the cooling medium (self-cooling, air-cooling, water-cooling). The main reasons for placing pebbles in the oil pit of the oil-immersed transformer are: fire prevention and oil drainage. This part ...

The load switch can’t directly replace the circuit breaker, but it can be used in conjunction with the high-voltage fuse. The main function of the switch is to break the circuit current, such as normal working current, short-circuit current, overload current and so on. For disconnecting hig...

The load switch is a switching appliance between the circuit breaker and the isolating switch. It has a simple arc extinguishing device, which can cut off the rated load current and a certain overload current, but cannot cut off the short-circuit current. The load switch is mainly used to break a...

A high-voltage load switch is an electrical appliance used to control power transformers, and its function is between high-voltage circuit breakers and high-voltage isolation switches. It is often used in series with high-voltage fuses. The high-voltage load switch utilizes the current-limiting f...

Oil-immersed transformer is a new type of high-performance transformer. Oil is used as the main insulation method of the transformer. The main components are composed of iron core, winding, radiator, etc., and are widely used in the power industry. Dry-type transformer is a transformer whose iron...

The working principle of a high voltage load switch is similar to that of a circuit breaker. Generally, a simple arc extinguishing device is installed, but its structure is relatively simple. The picture shows a compressed air high-voltage load switch. Its working process is: when the brake is op...
