The invention discloses a test machine for testing the opening and closing force of a disconnecting link. The test machine comprises a table top. A first supporting plate and a second supporting platewhich are parallel to each other are vertically and fixedly connected with the table top. A first guide rod is arranged on the first supporting plate in a sliding mode. A second guide rod coaxial with the first guide rod is arranged on the second supporting plate in a sliding mode. A hook is movably arranged at one end, away from the second guide rod, of the first guide rod. The opposite ends ofthe first guide rod and the second guide rod are respectively connected with a tension sensor through ropes. The tension sensor is in signal connection with a display. The test machine further comprises a power assembly installed on the table top and capable of driving the second guide rod to slide. The test machine further comprises an adjusting assembly arranged on the table top. A clamping assembly is installed on the adjusting assembly. According to the invention, the operation is simple and the labor force is saved. The test machine is accurate in measurement and is suitable for measuringthe clamping forces of large-scale and various types of high-voltage isolation switches.
Description
technical field [0001] The invention relates to the mechanical field, in particular to a knife switch opening and closing force testing machine. Background technique [0002] High-voltage isolating switch, commonly known as knife switch, is an important switching device in the electrical system of power plants and substations, and it needs to be used in conjunction with high-voltage circuit breakers. Its main functions are: to ensure the safety of high-voltage electrical appliances and devices during maintenance work, and to isolate the voltage. The main components of the high-voltage isolating switch are the static contact and moving contact assembly that are snap-fitted and connected, and the fixing plate for installing the above-mentioned components. , the pulling force required to pull the moving contact away from the static contact needs to be within a qualified range, so it is necessary to measure the clamping force of the high-voltage disconnector. The basic componen...
