Abstract
The utility model discloses a kind of gas-filling cabinet special isolation pull bar with shielding, belong to gas-filling cabinet technical field, it is characterized in that comprising high-pressure side metal insert (1), semiconductive material screen (2), epoxy resins insulation part (3), ground side metal insert (4), after high-pressure side metal insert (1) application semiconductive material screen (2) of described edge pull bar, mould is loaded together with ground side metal insert (4), and casting epoxy resin insulating part (3).Effect of the present utility model is: semiconductive material screen effectively reduce and even high-pressure side metal insert to the electric field strength of insulating part and ground side metal insert, add the reliability of product, stability, the striking distance of insulating part between high-low pressure metal insert under equal voltage is shortened greatly, under same dielectric intensity the volume of insulated tension pole reduce, weight saving.
Description
Technical field
The utility model belongs to gas-filling cabinet technical field, is specifically related to a kind of gas-filling cabinet special isolation pull bar with shielding.
Background technology
Current domestic gas insulation technology reaches its maturity, gas-filling cabinet product is flourish, the stability of the quality of element in cabinet, miniaturization, lightweight are had higher requirement, conventional insulated tension pole many employings metal insert direct pouring or be molded in the insulating material such as epoxy resin, DMC.Its shortcoming is that insert surface is rough, and easily form air gap between insulating part, electric field can be caused to concentrate, easily there is partial discharge between inserts and insulating part and finally make insulation breakdown in insulated tension pole, the qualified products high-pressure side insulating material under long-time running that dispatches from the factory is easily aging, is difficult to guarantee equipment long-term safety and runs.Above reason causes existing insulated tension pole volume larger, affect the carrying out of cabinet Miniaturization Design, in addition insulated tension pole weight is comparatively large on breaker mechanic property impact, and large weight insulated tension pole can make circuit-breaker switching on-off speed reduce, thus circuit breaker can not be cut-off rapidly when line fault.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of volume is little, lightweight, good insulation preformance, can the gas-filling cabinet special isolation pull bar of long-term, safety, reliability service in low-pressure insulating gas.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of gas-filling cabinet special isolation pull bar with shielding, it is characterized in that comprising high-pressure side metal insert (1), semiconductive material screen (2), epoxy resins insulation part (3), ground side metal insert (4), behind described high-pressure side metal insert (1) application semiconductive material screen (2), mould is loaded together with ground side metal insert (4), and casting epoxy resin insulating part (3), be coated with the semiconductive material screen that is contained on the metal insert of high-pressure side and conductively-closed inserts equipotential and with insulating part good contact, thus avoid, between high-pressure side metal insert and insulating part, partial discharge occurs, effectively reduce and even high-pressure side metal insert to the electric field strength of insulating part and ground side metal insert, add the reliability of product, stability, the striking distance of insulating part between high-low pressure metal insert under equal voltage is shortened greatly, under same dielectric intensity, the volume of insulated tension pole reduces, weight saving.
Adopt after technique scheme, the insulating barrier of insulated tension pole not easily puncture, not easily aging, add the reliability of product, stability.Under same dielectric grade, insulated tension pole can be accomplished: volume is less-meet the designing requirement of gas-filling cabinet miniaturization; Weight is lighter-improve breaker mechanic property parameter, reduce circuit breaker to the load of operating mechanism.
Accompanying drawing explanation
Fig. 1 is structural blast schematic diagram of the present utility model.
Fig. 2 is structure cutaway view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 (exploded perspective view), a kind of gas-filling cabinet special isolation pull bar with shielding, this insulated tension pole comprises high-pressure side metal insert (1), semiconductive material screen (2), epoxy resins insulation part (3), ground side metal insert (4) composition.First adhere to the thick semiconductive material screen of one deck 1 ~ 2mm in the right side of high-pressure side metal insert in the mode of application or die casting, the high-pressure side metal insert of band semiconductive material screen is loaded mould, casting epoxy resin insulating part (material) together with ground side metal insert.
As shown in Figure 2, after product cast molding, between high-pressure side metal insert and ground side metal insert, first there are one deck semiconductive material screen and a layer insulating.
