Abstract
The utility model discloses a long break distance air-actuated rotary type insulating switch which is used in electric power test and electric power equipment installation. The utility model comprises a fixed contact and a moving contact, as well as a fixed side end closure and a moving side end closure which are mutually insulated. The fixed contact is arranged on the fixed side end closure. The utility model is characterized in that an air-actuated type gearing connected with the moving contact is arranged on the moving side end closure, and the air-actuated type gearing drives the moving contact to make the beeline movement relatively to the fixed contact to realize the brake closing-separating of the switch. The utility model adopts the air-actuated rotary type gearing operation, and the closing-separating brakes of the moving contact and the fixed contact are driven through the rotation of a compressed airmotor. The problem that safety hidden trouble exists by adopting manpower to change the connection or adopting electromotion operation is solved. The utility model has the advantages that errors of the switch connection are not easy to happen, the working efficiency is improved and the work is reliable under high potential.

Technical field
The utility model relates to a kind of changing-over line isolating switch, particularly at power test, power equipment a kind of changing-over line isolating switch of usefulness is installed.
Background technology
The switch that need be operated in high potential in power test and power equipment are installed usually carries out reliable changing-over line to guarantee to test and equipment is installed carries out smoothly.That usually adopts is electric isolating switch or adopts artificial changing-over line, and wiring is unreliable like this, makes mistakes easily, and it is not high to exist potential safety hazard and operating efficiency to fall.
Summary of the invention
The technical problems to be solved in the utility model provides the large opening Pneumatic rotary isolating switch that uses in a kind of power test and the power equipment installation, has the characteristics of reliable operation under high potential.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of changing-over line isolating switch, comprise fixed contact and moving contact, have out apart from and the quiet side end cap and the moving side end cap of mutually insulated, described fixed contact is arranged on the quiet side end cap, it is characterized in that, described moving side end cap is provided with the pneumatic type transmission device that links to each other with moving contact, and the relative fixed contact moving linearly of this pneumatic type actuator drives moving contact is realized the closing of switch, separating brake.
In the such scheme, described pneumatic type transmission device comprises a runner and a guide wheel, described runner is connected with air motor axle on being arranged on moving side end cap, described guide wheel is arranged on the quiet side end cap, between runner and the guide wheel by a transmission rope interlock, moving contact connects this transmission rope and transmission rope is divided into two sections, and one section of the relative fixed contact direction of motion of moving contact is the insulation rope; Moving contact is a conductive cords back to a section of the fixed contact direction of motion.Also be provided with on the described quiet side end cap and be used for moving contact and fixed contact closes, two stroke valves of separating brake position.
The utility model has the advantages that, adopt pneumatic operation, isolating switch is fixed to assigned address, by tracheae source of the gas is incorporated into air motor, the air motor rotation drives the divide-shut brake that transmission rope is realized moving contact and fixed contact, solved and adopted artificial changing-over line to have the problem of potential safety hazard, operating efficiency improves; More reliable than the wiring of electrodynamic type switch, be not easy to make mistakes.
As further improvement, two terminal locations at switch are provided with the stroke valve, do chain and the signal indication so that the definite position usefulness gas signal of switch reached ground and convert the signal of telecommunication to, can carry out Long-distance Control and local operation.
