Abstract
The invention discloses a high-voltage switch sealing box which comprises an insulation box and a mechanism frame. A grounding fixed contact is installed in the insulation box, an isolating switch and a breaker are installed in the mechanism frame, a sealing element is arranged between the grounding fixed contact and the insulation box, a sealing element is arranged between the insulation box and the mechanism frame, a sealing element is arranged between a spindle of the isolating switch and the mechanism frame, a sealing element is arranged in a bearing block at the position where a transmission shaft of the isolating switch penetrates through the mechanism frame, a sealing element is arranged in a bearing block at the position where a transmission shaft of the breaker penetrates through the mechanism frame, sealing elements are arranged between a cover plate and the mechanism frame and between a rear sealing plate and the mechanism frame, the cover plate and the rear sealing plate are arranged on the mechanism frame, and a sealing element is arranged between a one-way valve arranged on the mechanism frame and used for detecting tightness of the mechanism frame and the mechanism frame. Compared with the prior art, the high-voltage switch sealing box solves the problem that insulating strength is declined because of moisture condensation, dust and the like in an existing ring main unit.
Description
Technical field
The present invention relates to electric power system equipment for power transmission and distribution manufacturing technology field, especially a kind of high-voltage switch gear seal case.
Background technology
In the existing power supply network system of China, for improving power supply reliability, usually power supply network is connected into annular, make the user obtain power supply from both direction, this supply power mode is referred to as ring network power supply.Ring main unit in ring network power supply equipment is core component, and described ring main unit can be divided into again air type ring main unit, SF6 gas-insulated ring network cabinet, solid insulation ring main unit etc. according to the difference of dielectric.Mechanism's frame of existing solid insulation ring main unit adopts the air insulation mode more; substantially relatively poor without sealing or sealing property; in various natural environmental conditions; described ring network cabinet body is inner often can to descend owing to the reasons such as dewfall, dust cause its dielectric strength; when situation is serious; may cause power outage, affect the normal safe operation of power supply network.
Summary of the invention
The purpose of this invention is to provide a kind of high-voltage switch gear seal case, it can reduce insulated case internal condensation and dust.
In order to address the above problem, the technical solution used in the present invention is: this high-voltage switch gear seal case, include insulated case and mechanism's frame, in described insulated case, grounding static contact is housed, in described mechanism frame, isolating switch and circuit breaker are housed, it is characterized in that: between described grounding static contact and described insulated case, be provided with seal, between described insulated case and described mechanism frame, be provided with seal, between the bearing cap of described isolating switch main shaft and described mechanism frame, be provided with seal, in passing the bearing pedestal at described mechanism frame place, the power transmission shaft of described isolating switch is respectively equipped with seal, in passing the bearing pedestal at described mechanism frame place, the power transmission shaft of described circuit breaker is provided with seal, between cover plate that described mechanism frame is provided with and rear shrouding and described mechanism frame, be provided with seal, described mechanism frame be provided with for detection of the unidirectional valve of its sealing and described mechanism frame between be provided with seal.
Owing to adopted such scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention can effectively reduce insulated case internal condensation and dust, thereby improves the operational reliability of product.
2, the present invention is simple in structure, and it is convenient to implement.
