Abstract
The invention relates to a pressure-operated load switch. The load switch is a switching appliance between a circuit breaker and an isolating switch and comprises a simple arc-extinguishing device, and rated load current and a certain overload current can be cut off, but short-circuit current cannot be cut off. The efficiency of an existing load switch is not the best in arc-extinguishing, so that arc-extinguishing effects can be further improved. The arc-extinguishing device is mounted at the right end of a switching device, a porcelain insulator (2) is mounted on the left of the switching device and on a base of the switching device, and the left of the base is connected with a spring A. The switching appliance is used for a power station.
Description
Technical field:
The present invention relates to a kind of pressure-operated load switch.
Background technology:
On-load switch is a kind of device for switching between circuit breaker and isolating switch, has simple arc-control device, can cut off rated load electric current and certain overload current, but can not cutting-off of short-circuit electric current.Existing on-load switch efficiency when arc extinguishing does not reach best effect, so arc quenching effect can further improve.
Summary of the invention:
The object of the present invention is to provide a kind of pressure-operated load switch.
The object of the present invention is achieved like this:
A kind of pressure-operated load switch, its composition comprises: arc-control device, and described arc-control device is arranged on the switching device right-hand member, and described switching device left side is equipped with porcelain vase, described installation of porcelain insulator is on the base of switching device, and described chassis left side is connected with spring A.
Described pressure-operated load switch, the cylinder interior of described arc-control device is equipped with piston, described piston base is connected with quadric chain, the connecting rod that described quadric chain is connected with piston is arranged on main shaft, described quadric chain is connected with the other end of spring A, the other end of described quadric chain is connected to the centre of main switch cutter, and the spout position, top of described cylinder is equipped with contact, and described contact top contacts with the arc extinguishing plug-in strip.
Described pressure-operated load switch, inlet wire is installed on the porcelain vase top of described switching device, described inlet wire upper end is the arc extinguishing plug-in strip fixedly, described main switch cutter is fixed on the arc extinguishing plug-in strip, be connected with spring B with the centre of arc extinguishing plug-in strip in the middle of described main switch cutter, described main switch cutter head section is equipped with main contact.
Beneficial effect:
1. the present invention carries out arc extinguishing by arc-control device is set, and reduces the generation of electric arc, reduces the infringement that electric arc produces.
2. the present invention, by mounting spring B between main switch cutter and arc extinguishing plug-in strip, is connected the arc extinguishing plug-in strip with the action of main switch cutter, strengthens arc quenching effect.
The accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present invention.In figure, 1 is insulated tension pole, and 2 is porcelain vase, and 3 is inlet wire, and 4 is the main switch cutter, and 5 is the arc extinguishing plug-in strip, and 6 is main contact, and 7 is contact, and 8 is spout, and 9 is outlet, and 10 is cylinder, and 11 is piston, and 12 is main shaft, and 13 is tripping spring.
