Abstract
The utility model relates to a novel single-pole isolating switch in a power supply circuit, which comprises a base, supporting insulators, a fixed contact, a movable contact and terminals, wherein one end of each supporting insulator is fixedly connected with the base, the other end of each supporting insulator is respectively provided with the terminals, the tail end of one supporting insulator is provided with the fixed contact, the tail end of the other supporting insulator is movably connected with the movable contact, the other end of the movable contact is movably connected with the fixed contact head, one side of the base is provided with a connecting rod, and the tail end of the connecting rod is provided with an installing hole. The utility model has the advantages that: firstly, large-load current can pass through the novel single-pole isolating switch; secondly, the outdoor direct-hanging type single-pole isolating switch can be conveniently installed, can be arranged on a cross arm, is fixed and firm and can save time and materials at the same time; and thirdly, owing to a slant angle, an operator can more safely and conveniently use an insulating bar to operate.
Description
One, technical field:
The utility model relates to isolator operation device used in a kind of supply line, particularly a kind of novel single-pole isolator.
Two, background technology:
Outdoor monopolar high-voltage isolating switch is a kind of electric switch that is widely used on the high pressure electric line, it and distribution transformer, high-tension fuse, high-tension oil switch and High-voltage measuring box are used, in order to the single-phase and three-phase circuit that cuts off, closed zero load is loaded, have simple in structure, handling safety, advantage easy to maintenance, but existing outdoor monopolar high-voltage isolating switch is because the defective on structural design, also there is weak point: can not pass through big load current, can not on a cross-arm, install, installation is wasted time and energy, and dangerous.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of simple and fast, practical, novel single-pole isolator that coefficient of safety is high are provided.
Its technical scheme is: comprise base, supporting insulator, fixed contact, moving contact, terminals, one end of described two supporting insulators is connected and fixed with base respectively, the other end of each supporting insulator is respectively equipped with terminals, the end of one of them supporting insulator is provided with fixed contact, the end of another supporting insulator flexibly connects moving contact, the other end of moving contact and fixed contact flexibly connect, one side of described base is provided with connecting rod, and the end of described connecting rod is provided with installing hole.
Above-mentioned connecting rod and base are the angle of 10-90 degree, are preferably miter angle.
The beneficial effects of the utility model are: 1, can pass through big load current.2, outdoor direct hanging type single-pole isolator is easy for installation, can install on a cross-arm, and is fixing firm, saves time simultaneously, material-saving.3, because the inclination angle is arranged, make personnel safer when using the insulating rod operation, convenient.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
Its technical scheme is: comprise base 4, supporting insulator 3, fixed contact 2, moving contact 1, terminals 6, one end of described two supporting insulators 3 is connected and fixed with base respectively, the other end of each supporting insulator 3 is respectively equipped with terminals 6, the end of one of them supporting insulator 3 is provided with fixed contact 2, the end of another supporting insulator 3 flexibly connects moving contact 1, the other end of moving contact 1 and fixed contact flexibly connect, one side of described base 4 is provided with connecting rod, the end of described connecting rod is provided with installing hole 5, described connecting rod and base 4 are the angle of 10-90 degree, are preferably miter angle with reference to accompanying drawing.
The utility model is for the single-phase use of three-phase line system, and is promptly simple in structure, economical, easy to use.Adopt guillotine type structure divide-shut brake to disconnect and closed circuit, every phase brake lining is made up of two conductive blades, and the compression spring is housed outside the blade both sides, and the height of regulating spring can arrive the needed contact pressure of isolating switch plug-in strip.During the switch divide-shut brake, do just can carry out the on/off switch motion with the insulated hook clubs, isolation switch blade has locking device.
One 45 ° inclination angle is arranged after the repacking, more convenient to operate, safe and reliable, and changed traditional mounting means; This isolating switch can replace GW9-12/400,630 and HGW9-12/400, type of isolation switches such as 630.This class isolating switch can be installed on a cross-arm, and is very convenient, fixing also relatively more firm, and the material-saving that saves time (can save a cross-arm, 3 width of cloth isolation switch fixed supports).In addition, because 45 ° angle of inclination is arranged, make the operating personnel safer when using the insulating rod operation, than before handling safety coefficient below isolating switch higher.
