Abstract
The utility model relates to a high-voltage disconnecting switch for high-voltage transmission and distribution, in particular to a sulfur hexafluoride high-voltage disconnecting switch, comprising a body case composed of an upper case and a lower case both made of insulation materials. The upper case and the lower case are hermetically connected with each other to form a sealed inner chamber which is filled with sulfur hexafluoride gases; three phase upper static contacts and three phase lower static contacts are arranged in the inner chamber, and three phase movable contact cutters are arranged between the upper and the lower static contacts. The end of each movable contact cutter is hinged with the corresponding lower static contact. The upper and the lower static contacts are separately connected with an upper wire connection terminal and a lower wire connection terminal which are extended out of the body case. A drive shaft is connected with the movable contact cutter through a driving crank arm and a hinged connecting rod. The left side of the lower static contact is also provided with three phase grounding contacts. The utility model has good insulating property, compact structure and little space occupying.
Description
Technical field
The utility model relates to a kind of high pressure power transmission and distribution high voltage isolator that is used for, and specifically is a kind of sulphur hexafluoride insulation high voltage isolator.
Background technology
The existing high voltage isolator that is used for three-phase electrical power system generally adopts air insulation, for guaranteeing the class of insulation, its phase spacing is bigger, simultaneously in the isolating switch of traditional structure, the spatial dimension of each parts operation is also bigger, cause the overall dimensions of switch and in switchgear required installing space all bigger, thereby increased the space hold of high voltage switchgear, be difficult to the substation that is applicable to that some spaces are nervous.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of good insulation preformance, while compact conformation, the sulphur hexafluoride insulation high voltage isolator that takes up room little.
Sulphur hexafluoride insulation high voltage isolator of the present utility model includes a housing of being made up of the upper casing and the lower casing of insulating material, is tightly connected between the upper and lower shell, constitutes the inner chamber of a sealing, is filled with sulfur hexafluoride gas in the inner chamber of sealing; Being provided with fixed contact under three-phase upper static contact and the three-phase in the inner chamber, is the three-phase movable touch knife between the upper and lower fixed contact, and every phase movable touch knife lower end is with corresponding fixed contact is hinged down, upper and lower fixed contact respectively with stretch out housing outside last terminals be connected with following terminals; Have a power transmission shaft vertically to pass inner chamber from the right side of upper and lower fixed contact, power transmission shaft is connected with movable touch knife with hinged connecting rod by transmission crank arm; Left side at following fixed contact also is provided with the three-phase grounding contact.In addition, also can be provided with lower casing in the lower casing bottom outside and to be linked as three whole insulating cylinders, they are looped around respectively under the three-phase around the terminals, with the insulating properties between wild phase.
The utility model compact conformation, reasonable, when guaranteeing the good insulation performance, dwindle taking up room and the installation and operation space in switchgear of whole device greatly, when using it in the switchgear, helped saving the overall space of switchgear.
