Abstract

The invention discloses a testing device for a relay protection outlet circuit. The testing device comprises a casing and a testing module arranged in the casing, wherein a plurality of measuring terminals for being connected with the testing module are arranged on the enclosing wall of the casing; the testing module comprises a touch display screen arranged on the surface of the casing, a processor which is arranged in the casing and used for carrying out data processing, a rechargeable battery which is arranged in the casing and used for providing electric energy, a charging controller communicated with the rechargeable battery as well as a thermal balance adjusting module connected with the processor. The thermal balance adjusting module and a dynamic balancing mechanism are arranged in the device and can be used for protecting the device, so that the device can be kept in a stable environment, and the phenomenon of internal damage due to missing fall can be avoided.

Description

technical field [0001] The invention relates to the technical field of relay protection devices, in particular to a relay protection outlet circuit testing device. Background technique [0002] With the rapid development of the power system, the scale of the power grid is growing day by day, and the network structure of the power system is more complex. It is particularly important to improve the safe operation level of the power system. Due to the particularity of the power system, the occurrence of electrical faults is inevitable. During the operation of the power system, if a local power grid or electrical equipment accident occurs and cannot be effectively controlled, it will inevitably cause damage to the stability of the power grid and a large-scale blackout accident; modern large power grids are more dependent on relay protection. The requirements for the correct rate of its movements are higher. [0003] The relay protection device is an important part of the power...
