Abstract

The invention discloses a detection device for a relay protection device in an electric power system. The invention can realize the automatic flow-through detection of the relay protection device, improve the detection efficiency, and the conveying mechanism automatically transports the relay protection device, and utilizes the detection The detection circuit in the mechanism is automatically detected. During the detection, the detection access terminal of the detection circuit is connected to the terminal of the relay protection device to be detected under the control of the access circuit control mechanism, so as to realize the relay protection to be detected. The automatic and rapid detection of the device can realize the effect of pushing out unqualified products. The detection mechanism is adjusted horizontally and vertically to adapt to different types of relay protection devices and improve applicability; the detection circuit of the present invention controls There are at least a protective circuit breaker and a short-circuit controller connected in series inside the device. When the relay protection device to be detected is unqualified and cannot be disconnected, the protective circuit breaker can be automatically disconnected to protect the detection circuit controller.

Description

technical field [0001] The invention relates to an auxiliary device for a relay protection device, in particular to a detection device for a relay protection device of an electric power system. Background technique [0002] In the power system, the relay protection device is widely used, and it can protect the circuit well in the event of a short circuit. Therefore, in most power occasions, relay protection devices are required for protection, and relay protection devices need to be tested after production. The current detection devices have a relatively simple structure and are generally detected manually. Detection is not only inefficient, but also has potential safety hazards. [0003] Therefore, the present invention provides a detection device for a relay protection device of an electric power system to solve the problems raised in the background art above. Contents of the invention [0004] The object of the present invention is to provide a detection device for a ...
