Description
Technical field
The utility model relates to a kind of control device on the High-Voltage Electrical Appliances in the electric utility, particularly a kind of 10kV gas-filling cabinet on-load switch.
Background technology
The 10kV gas-filling cabinet is the totally-enclosed charger of stainless steel that adopts welding, inflation, leak hunting technology to produce, and its all live parts all are sealed in the Stainless Steel Shell that is filled with sulfur hexafluoride gas.But adopt modularized design not only compactness but also independent assortment, expansion, flexible design.Product is applied to construction and the transformation of urban distribution network, is applicable to the power supply of the ring network power supply of each distribution system and terminal, also is suitable for pack into easy assembling type transformer station, power distribution station, has totally-enclosed, non-maintaining, compact conformation, characteristics that reliability is high.
On-load switch is a main element in the 10kV gas-filling cabinet, plays a part to connect and cut-off load current, forms two fractures when disjunction, plays the effect of isolated high-voltage power supply, guarantees safety.Because on-load switch is installed in the 10kV gas-filling cabinet, so want cube little, be easy to install; Finding out from the interaction energy of on-load switch, for guaranteeing safety, require the security performance of on-load switch very high, also is not very perfect but existing on-load switch does in security performance.
Summary of the invention
For the requirement of 10kV gas-filling cabinet and the defective of existing on-load switch, the utility model provides a kind of 10kV gas-filling cabinet on-load switch.
To achieve these goals, the utility model institute Adopts measure is:
A kind of 10kV gas-filling cabinet on-load switch, comprise the body that is connected on the gas-filling cabinet header board inwall, body is to cooperate a casing that forms by upper shell and lower house, be provided with fixed contact and moving contact in the casing, be fixed with upper static contact on the inwall of upper shell, be fixed with lower fixed contact with the upper static contact corresponding position on the lower house inwall, be fixed with rotating shaft between upper shell and the lower house, position corresponding with fixed contact in the rotating shaft is fixed with moving contact, and rotating shaft links to each other with load switch operation mechanism on being arranged on gas-filling cabinet header board outer wall;
Described upper shell and lower house are epoxy resin poured body;
The arranged outside of described upper shell and lower house has several protruding dividing plates, and dividing plate is between adjacent fixed contact;
Described upper static contact and lower fixed contact are the three-phase contact;
The front end of described upper static contact and lower fixed contact is bulge-structure;
The two ends of described moving contact are provided with the groove that the projection with fixed contact is complementary;
The material of described rotating shaft is for strengthening nylon.
The beneficial effects of the utility model: upper-lower casing adopts poured with epoxy resin, and upper-lower casing consistent size, intensity are good, the convenient installation, and applicable row is strong; The up and down mode of fixed contact of while break-make is adopted in arranging of moving contact, and insulation and the arc extinguishing effect of sulfur hexafluoride gas are arranged, thereby the break-make performance is more excellent; The dividing plate of projection is set on upper shell and the lower house, can gains in strength and increase the surface creepage distance, safe and reliable.
Description of drawings
The structural representation of Fig. 1, the utility model embodiment.
Embodiment
Embodiment (such as Fig. 1), a kind of 10kV gas-filling cabinet on-load switch, comprise the body that is connected on gas-filling cabinet header board 1 inwall, body is to cooperate a casing that forms by upper shell 2 and lower house 6, be provided with fixed contact and moving contact 8 in the casing, be fixed with upper static contact 3 on the inwall of upper shell 2, be fixed with lower fixed contact 4 with upper static contact 3 corresponding positions on lower house 6 inwalls, be fixed with rotating shaft 5 with bolt between upper shell 2 and the lower house 6, consist of load switch body, axis adopts and strengthens nylon material, when guaranteeing its mechanical performance, possess again very strong insulation property, the position corresponding with fixed contact is fixed with moving contact 8 in the rotating shaft 5, and rotating shaft 5 links to each other with load switch operation mechanism 7 on being arranged on gas-filling cabinet header board 1 outer wall; Described upper shell 2 and lower house 6 are epoxy resin poured body; The arranged outside of described upper shell 2 and lower house 6 has several protruding dividing plates 9, and dividing plate 9 is between adjacent fixed contact; Described upper static contact 3 and lower fixed contact 4 are the three-phase contact; The front end of described upper static contact 3 and lower fixed contact 4 is bulge-structure; The two ends of described moving contact 8 are provided with the groove that the projection with fixed contact is complementary; The material of described rotating shaft 5 is for strengthening nylon; Be filled with sulfur hexafluoride gas in the gas holder, play the effect of insulation and arc extinguishing.
In the use procedure, by load switch operation mechanism 7 rotating shafts 5, the moving contact 8 in the rotating shaft 5 rotates thereupon, can control being connected and separating of moving contact 8 and fixed contact, realizes closure and the disconnection of switch.
The beneficial effects of the utility model: upper-lower casing adopts poured with epoxy resin, and upper-lower casing consistent size, intensity are good, the convenient installation, and applicable row is strong; The up and down mode of fixed contact of while break-make is adopted in arranging of moving contact, and insulation and the arc extinguishing effect of sulfur hexafluoride gas are arranged, thereby the break-make performance is more excellent; The dividing plate of projection is set on upper shell and the lower house, can gains in strength and increase the surface creepage distance, safe and reliable.
