For achieving the above object and adopt technical solution be such: the large capacity function composite high-pressure metal sealing switch equipment contact box providing has a hood-shaped insulation box body, be provided with major loop conductive mounting inserts at insulation box body central upper portion position, this conductive mounting inserts upper and lower end face has support and connection concurrently longitudinal rotary isolation circuit breakers fixed contact and the main bus bar that once confluxes is installed, the left and right sides that is positioned at isolation circuit breakers fixed contact in insulation box body is separately installed with pectination heat abstractor, be provided with ventilation and heat water conservancy diversion angle at the heat dissipation direction place of this heat abstractor, be provided with at the rear side of box body the connection square opening and the air intake passage that are connected with drawer type heat abstractor in high-pressure metal enclosed switch cabinet.
Technical solution of the present invention is also: the round boss that the left and right sides of insulation box body bottom respectively has respectively two precise positionings to install, the left and right and rear wall of insulation box body bottom is provided with circle limit, insulation booth cavity location.
Technical solution of the present invention is also: the relative baseplane of trailing flank of insulation box body is 5 °～15 ° overturning angles, the insulation leading flank of box body and the corresponding arc surface that is of the rotational trajectory of isolation circuit breakers.
Technical solution of the present invention is also: the left and right sides, top at insulation box body is provided with ventilation and heat water conservancy diversion angle, in ventilation and heat water conservancy diversion angle, is provided with reinforcement.
Technical solution of the present invention is also: be provided with at the rear wall of insulation box body the connection square opening and the air intake passage that are connected with drawer type heat abstractor in the installation of high-pressure metal enclosed switch cabinet, air intake passage forms unobstructed internal heat dissipating passage by pectination heat abstractor and ventilation and heat water conservancy diversion angle.
Technical solution of the present invention is also: the cup-shaped structure of major loop conductive mounting inserts arranging at the central upper portion position of insulation box body.
Compared with prior art, the beneficial effect that the present invention has is:
1, a hood-shaped insulation box body of invention design, box body central upper portion position is provided with cup-shaped major loop conductive supporting inserts, this cup insert has crosslinked support and connection concurrently longitudinal rotary isolation circuit breakers fixed contact and the transverse horizontal main bus bar that confluxes is installed, having save main bus bar is connected and supports with the transition between branch bar, and then eliminated that prior art exists because of major loop path length, electrically connect with insulating supporting point many, the high material consumption that the unreasonable structures such as circuit is irregular cause, take up room large, loop contact resistance is large, temperature rise, power loss is large, hot corrosion and aging serious and electrically connect many drawbacks such as internal field too concentrates,
2, the present invention is separately installed with pectination radiator in the isolation circuit breakers fixed contact left and right sides of conductive supporting inserts bottom connection, the ventilation and heat water conservancy diversion angle that the heat dissipation direction of radiator is provided with corresponding to this contact box body top, inserts left and right sides, air intake passage in the rear side setting of hood-shaped insulation box body forms by pectination heat abstractor and ventilation and heat water conservancy diversion angle the internal heat dissipating passage that air confluxes unobstructed in length and breadth, this creationary project organization is in high-tension switch cabinet, mainly warm area---the heat radiation at fingertip interlock position and the heat radiation of global switch cabinet of main switch have significant advantage, this is also that this area is broken through traditional closed contact box structure design first, to reducing high-current switch equipment major component, vital effect has all been played in the temperature rise of major loop and Whole Equipment, also be the emphasis innovation that the present invention solves high-current switch equipment thermal field effect.
3, design of the present invention is unique, simple in structure and rationally compact, product integrates that conductor insulation supports, electrically connects, heat loss through convection etc. is multi-functional, not only greatly dwindle physical dimension, copper material, steel and organic insulating material, minimizing floor space are saved in a large number, and effectively cracked the 'bottleneck' restrictions of high-current switch equipment thermal field effect, there is remarkable Technological Economy meaning.
