Isolation switch apparatus

Abstract

An isolating switch device, including a bracket and several arc extinguishing devices arranged on the bracket, and also includes several sliding risers sleeved on the bracket and perpendicular to the bracket, the middle part of the sliding riser is provided with a mounting hole, the sliding vertical plate is sleeved on the bracket through the mounting hole, a width adjustment mechanism is provided between any two sliding vertical plates, and an arc extinguishing device is correspondingly provided on each sliding vertical plate. The device comprises a fixed insulating porcelain bottle arranged at one end of a sliding vertical plate, a rotating insulating porcelain bottle arranged at the other end of a sliding vertical plate, and a disconnection control device arranged between the fixed insulating porcelain bottle and the rotating insulating porcelain bottle. Compared with the prior art, the present invention , By optimizing the installation position of the arc extinguishing chamber, the overall safety performance of the device is improved, and by optimizing the main structure of the bracket, the practicability is also greatly improved.

Description

technical field [0001] The invention relates to a switch device used on a high-voltage line, in particular to an isolating switch device. Background technique [0002] After most of the rural and remote areas in China have been electrified, most of the high-voltage isolating switches, short circuit breakers and other electrical equipment have been placed outdoors for a long time, and are distributed in various streets, urban-rural junctions, rural areas, etc., and cannot be managed and maintained uniformly. If it is not good, it will damage the adjacent electrical equipment due to excessive temperature during operation. [0003] At present, the isolating switch is a kind of control switch with the simplest structure and widely used in hand-controlled electrical appliances. It is mainly used for infrequently connecting and breaking low-voltage circuits with small capacity or directly starting small-capacity motors. The main function is to isolate the power supply to ensure t...

Problems solved by technology

[0002] After most of the rural and remote areas in China have been electrified one after another, most of the high-voltage isolating switches, short circuit breakers and other electrical equipment have been placed outdoors for a long time, and are distributed in various streets, urban-rural junctions, rural areas and other places, which cannot be managed and maintained uniformly. Inadequate, damage to adjacent electrical equipment due to excessive temperature during operation

[0003] At present, the isolating switch is a kind of control switch with the simplest structure and widely used in the hand-controlled electrical appliances. The main function is to isolate the power supply to ensure the safety of circuit and equipment maintenance and to break the load. However, due to the imperfect design of the existing isolating switch, it has the following defects: First, it is used in medium and high voltage circuits. The current is large, and a high-energy arc will be generated at the same time of breaking, which will pose a great danger to the equipment. Second, in some special environments, it is necessary to fine-tune the position of the insulating porcelain bottle, but due to They are all fixed together and cannot be adjusted, so they are less practical
