Abstract

The invention relates to a test instrument, and is particularly suitable for testing an arc suppression coil compensation device. Aiming to solve the problem that at present arc suppression coil compensation devices are installed in many substations, while, except for the operation indication signal provided by the manufacturer, the device is lack of a monitoring means from the third party for monitoring the running state, the invention discloses a test instrument for the arc suppression coil compensation device, which includes an output end and an input end both connected with a central processor, wherein the output end includes a zero sequence voltage signal module, a zero sequence current signal module, a power network voltage signal module and a gear signal module; the input end of the test instrument includes a gear adjustment signal module and a damping resistance control signal module; and the central processor is connected with a power supply module and a human-computer interface module and the like respectively. The test instrument provided by the invention provides a testing means for the arc suppression coil compensation device, and guarantees the safety operation of the power network.

Description

technical field [0001] The invention relates to a tester, which is especially suitable for testing arc suppression coil compensation devices. Background technique [0002] At present, most of the distribution network adopts the method of grounding through arc suppression coils. With the extensive use of cables, many substations have installed arc suppression coil automatic compensation devices. In addition to signals, there is a lack of third-party monitoring means. Therefore, people are eager to have a means to test the arc suppressing coil automatic compensation device. Contents of the invention [0003] The purpose of the present invention is to provide a means for testing the arc suppressing coil automatic compensation device. [0004] The technical solution of the present invention is a tester for an arc suppression coil compensation device, which is characterized in that it is composed of an output terminal and an input terminal connected to a central processing un...
