Abstract
The utility model relates to a testing device of low voltage power transmission and distribution equipment, specifically relates to a clamp for testing the operating force of a moulded case circuit breaker. The clamp for testing the operating force of the moulded case circuit breaker comprises a mounting rack. A stopper is arranged on the front of the bottom of the mounting rack. A clamping cylinder which is matched to a front stopper to clamp fixedly the moulded case circuit breaker to be tested is arranged on the back of the bottom of the mounting rack. A brake opening and closing cylinder is arranged on the rear portion of the mounting rack. A telescoping end of the divide-shut brake cylinder is connected to a claw through a force cell, and the claw is driven to move reciprocatingly by the divide-shut brake cylinder. The claw is provided with a clamping groove which is matched to a damage handle of the moulded case circuit breaker prepared to be tested and operates the handle to open and close a brake. The clamp for testing the operating force of the moulded case circuit breaker has simple structure and convenient operation. By adopting an electronic force measuring system to test the operation force of opening and closing the brake, the testing result accuracy is high, and the clamp for testing the operating force of the moulded case circuit breaker is convenient to connect with an intelligence control system to raise the testing efficiency.

Technical field
The utility model relates to a kind of proving installation of low pressure equipment for power transmission and distribution, specifically a kind of breaker of plastic casing operating physical force test fixture.
Background technology
The operating physical force of breaker of plastic casing is one of detection index of its product, main by manually detecting at present.Testing staff needs hand to take weight beam to hook operating grip, and manual measurement, reads numerical value.Labour intensity is large, and efficiency is lower, measures also inaccurate.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of simple in structure, easy to operate, detect accurately, breaker of plastic casing operating physical force test fixture that efficiency is high.
Breaker of plastic casing operating physical force test fixture of the present utility model includes an erecting frame, and the bottom front of erecting frame is provided with limited block, and rear end, erecting frame bottom is provided with and can coordinates with positive stop the gripper cylinder that breaker of plastic casing to be measured is gripped; Erecting frame rear portion is provided with a divide-shut brake cylinder, the telescopic end of divide-shut brake cylinder connects one by a force cell can be by its claw moving back and forth of divide-shut brake air cylinder driven, on claw, be provided with the draw-in groove coordinating with the damage handle of breaker of plastic casing to be measured, being used for operating grip carries out breaking-closing operating.
On described erecting frame, be provided with the longitudinal rail of a level, described claw cooperation is arranged on longitudinal rail and in the spacing lower rectilinear movement of longitudinal rail.
The electronic dynamometer being connected with force cell is installed on described erecting frame, is used for showing detection numerical value.
The utility model is simple in structure, easy to operate, and it detects breaking-closing operating power by electronics dynamometric system, and not only testing result accuracy is high, and is conveniently connected to improve detection efficiency with intelligent control system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
