Abstract
The utility model discloses a box body for sealing a high-voltage switch. The box body comprises an insulating box and a mechanism frame, wherein a grounding static contact is arranged in the insulating box; an insulation switch and a circuit breaker are arranged in the mechanism frame; sealing pieces are arranged between the grounding static contact and the insulating box, between the insulating box and the mechanism frame and between a bearing cover of an isolation switch main shaft and the mechanism frame; a sealing piece is arranged in a bearing pedestal through which a transmission shaft of the isolation switch penetrates at the mechanism frame; a sealing piece is arranged between a cover plate and a rear sealing plate which are arranged on the mechanism frame and the mechanism frame; and a sealing piece is arranged between a check valve which is arranged on the mechanism frame and is used for detecting the sealing performance of the mechanism frame and the mechanism frame. Compared with the prior art, the box body has the advantage that the problem of the reduction of insulation strength due to moisture condensation, dust and the like in the conventional ring main unit is solved.
Description
Technical field
The utility model 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 existing power supply network system, for improving power supply reliability, usually power supply network is connected into to annular in China, 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 poor without sealing or sealing property; in various natural environmental conditions; described ring network cabinet body is inner often can descend because 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.
The utility model content
The purpose of this utility model is to provide a kind of high-voltage switch gear seal case, and it can reduce insulated case internal condensation and dust.
In order to address the above problem, the technical solution adopted in the utility model 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, 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, power transmission shaft at described isolating switch is respectively equipped with seal through in the bearing pedestal at described mechanism's frame place, power transmission shaft at described circuit breaker is provided with seal through in the bearing pedestal at described mechanism's frame place, be provided with seal between the cover plate be provided with and rear shrouding and described mechanism frame on described mechanism frame, be provided with seal between the unidirectional valve for detection of its sealing be provided with and described mechanism frame on described mechanism frame.
Owing to having adopted such scheme, the utility model compared with prior art has following beneficial effect:
1, the utility model can effectively reduce insulated case internal condensation and dust, thereby improves the operational reliability of product.
2, the utility model is simple in structure, and it is convenient to implement.
The accompanying drawing explanation
Fig. 1 is that master of the present utility model looks schematic diagram.
The left view that Fig. 2 is Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Described high-voltage switch gear seal case of Fig. 1 and Fig. 2, include insulated case 8 and mechanism's frame 9, grounding static contact 1 is housed in insulated case 8, isolating switch and circuit breaker are housed in mechanism's frame 9, be provided with " O " RunddichtringO between grounding static contact 1 and insulated case 8, be provided with " O " RunddichtringO between insulated case 8 and mechanism's frame 9, be provided with " O " RunddichtringO between the bearing cap 3 of isolating switch main shaft and mechanism's frame 9, power transmission shaft at isolating switch is provided with " O " RunddichtringO through in the bearing pedestal 4A at mechanism's frame 9 places, power transmission shaft at circuit breaker is respectively equipped with the lip-type seal part through in the bearing pedestal 4B at mechanism's frame 9 places, be provided with " O " RunddichtringO between the cover plate 5 be provided with and rear shrouding 7 and mechanism's frame 9 on mechanism's frame 9, be provided with " O " RunddichtringO between the unidirectional valve for detection of its sealing 6 be provided with and mechanism's frame 9 on mechanism's frame 9.
