Abstract

The invention discloses an experimental device for a distribution line overvoltage protector. The experimental device comprises a bottom disc, wherein a box body is sleeved in the bottom disc, the lower end of the box body is provided with a sliding plate, the left and right sides of the upper part of the bottom disc are provided with anti-dropping plates, a buffer spring is arranged between the sliding plate and each of the two anti-dropping plates, a first terminal is arranged at the left side of the upper end of the box body, a second terminal is arranged at the right end of the first terminal on the upper end of the box body, a third terminal is arranged at the right end of the second terminal on the upper end of the box body, and a fourth terminal is arranged at the right side of theupper end of the box body. During operation, a screw rod rotates in a vertical plate and drives a cylinder to move leftwards and rightwards, and a contact at the lower end of a connecting rod can be in contact with the plurality of terminals in sequence, thereby accelerating the speed of the experiment and improving the efficiency of the experiment. A travelling wheel slides in a top slot, the contact moves more steadily, and the screw rod can save manual contact with the contact, thereby avoiding a safety accident caused by electric leakage, and improving the usage safety of equipment.

Description

technical field [0001] The invention relates to the technical field of experimental devices, in particular to an experimental device for an overvoltage protector of a distribution line. Background technique [0002] The overvoltage protector is an advanced protective device that limits lightning overvoltage and operating overvoltage. The overvoltage protector is a new type of overvoltage protector, which is mainly used to protect the insulation of electrical equipment such as generators, transformers, vacuum switches, busbars, and motors from overvoltage damage. The overvoltage protector, also known as the three-item combined overvoltage protector, is used to limit atmospheric overvoltage, vacuum circuit breaker operating overvoltage and various transient overvoltages in the power system. Overvoltage protectors can effectively protect phase-to-ground and phase-to-phase overvoltages. When the voltage is abnormal, the power supply can be quickly disconnected to prevent overv...
