Abstract
The utility model relates to an outdoor direct-hanging type single-pole isolating switch in a power supply circuit, which comprises a supporting insulator, a fixed contact, a movable contact, two terminals and supporting frames, wherein both ends of the supporting insulator are respectively connected with the supporting frames, the tail end of one supporting frame is connected with the terminals and the fixed contact, the tail end of the other supporting frame is connected with the terminals and the movable contact, the other end of the movable contact is movably connected with the fixed contact, the middle of the supporting insulator is provided with a base bracket, and the tail end of the base bracket 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 outdoor direct hanging type 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, outdoor direct hanging type single-pole isolator that coefficient of safety is high are provided.
Its technical scheme is: comprise supporting insulator, fixed contact, moving contact, two terminals, bracing frame, the two ends of described supporting insulator connect bracing frame respectively, the end of one of them bracing frame connects terminals and fixed contact, the end of another bracing frame connects terminals and moving contact, the other end of moving contact and fixed contact flexibly connect, the centre of described supporting insulator is provided with base support, and the end of base support is provided with installing hole.
Above-mentioned base support and supporting insulator are the angle of 10-90 degree.
A kind of scheme is that terminals and fixed contact are installed together, and another terminals and moving contact link together.
Another kind of scheme is that two terminals are connected on the bracing frame along the vertical direction of bracing frame respectively.
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 (can save a cross-arm, 3 pairs of isolation switch fixed supports).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;
Accompanying drawing 2 is structural representations of another kind of embodiment 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 supporting insulator 3, fixed contact 2, moving contact 1, two terminals 6, bracing frame 7, the two ends of described supporting insulator 3 connect bracing frame 7 respectively, the end of one of them bracing frame connects terminals 6 and fixed contact 2, the end of another bracing frame connects terminals 6 and 1, one terminals of moving contact and fixed contact 2 and is installed together, and another terminals and moving contact 1 link together; The other end of moving contact 1 and fixed contact flexibly connect, and the centre of described supporting insulator 3 is provided with base support 4, and the end of base support is provided with installing hole 5.Described base support and supporting insulator 3 are the angle of 10-90 degree, with reference to accompanying drawing 1, are preferably miter angle.
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.
