Abstract

The invention relates to a resetting device for a protection and monitoring apparatus of a transformer station, specifically a device for the wireless resetting of a protection signal of the transformer station. The device comprises a main controller and a receiving executor. The main controller comprises a first power management unit, a first MCU main control unit, a first ISM frequency-band radio-frequency receiving and transmitting unit, a GSM / CDMA wireless data transmission unit, and an input / output interface unit. The receiving executor comprises a second power management unit, a second MCU main control unit, a second ISM frequency-band radio-frequency receiving and transmitting unit, and an exit relay unit. In order to solve the problems that the construction of a remote signal resetting mode of a conventional transformer station is difficult and the maneuverability is low, the invention proposes the resetting device. The resetting device controls the main controller through a remote control dry contact of a public measurement and control screen, and the main controller communicates with the receiving executor disposed on the protection and monitoring apparatus in a wireless mode and transmits an instruction to enable a reset circuit to be connected, thereby enabling achieving the resetting of a signal of the protection and monitoring apparatus.

Description

technical field [0001] The invention relates to a reset device for a substation protection measurement and control device, in particular to a wireless reset device for a substation protection signal. Background technique [0002] At present, there are two methods for remote reset of substation protection signals. One way is that the manufacturer of the monitoring background and the protection measurement and control device are the same manufacturer, and the measurement and control device has the function of remote reset signal. The two can reset the protection through Ethernet software protocol communication. In fact, at least 80% of substation monitoring backgrounds and protection measurement and control devices are not from the same manufacturer, or although they belong to the same manufacturer, the measurement and control devices do not have the remote reset function; It is realized by laying cables between the measurement and control devices. This method increases the ca...
