A small high voltage isolating switch

Abstract

The invention discloses a small high-voltage isolating switch. An operation mechanism is arranged on a cover plate of a high-voltage silicon rectifier transformer; the operation mechanism comprises a center shaft, a locking plate, an insulator, a shaft sleeve, a guide rod, a copper clamp and an insulation supporting plate; a safe interlocking assembly comprises a limiting plate and a stroke switch; the center shaft comprises an upper shaft and a lower shaft; the shaft sleeve sleeves the upper shaft which can rotate relative to the shaft sleeve; the upper shaft and the lower shaft are connected with the insulator; the lower shaft is connected with the horizontal guide rod; the upper end of the upper shaft is provided with the locking plate; one end of the locking plate is provided with a shifting piece; the shifting piece arranged on the locking plate and the guide rod arranged on the lower shaft are towards the same direction; the upper shaft penetrates the cover plate of the high-voltage silicon rectifier transformer from bottom to top. According to the small high-voltage isolating switch, the problems of the complex structure, the large occupied space, the inconvenient installation and use and the high production cost of the traditional high-voltage isolating switch are effectively solved, the structure is simple, the use is safe and reliable, and the cost is low.

Description

technical field [0001] The invention relates to an isolating device, in particular to a small high-voltage isolating switch suitable for high-voltage electrostatic dust removal of 10 kV and below. Background technique [0002] At present, the general-purpose high-voltage isolation protection for high-voltage electrostatic precipitators of 10 kV and below is to install a bulky high-voltage isolation switch at the output end of the high-voltage power supply, and isolate the high voltage by operating the connection and disconnection of the high-voltage isolation switch. for protection purposes. However, the disadvantages of the above isolating switch are complex structure, large space occupation, inconvenient installation and use, and high production cost. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, and provide a small high-voltage isolating switch with simple structure, safety and reliability, lo...
