Problems solved by technology

[0004] However, the monitoring of the operation information of the protection device by the intelligent dispatching technical support system is limited to prompting whether the protection device is in normal operation, and cannot carry out real-time monitoring and effective control of the actual operation status of the secondary pressure plate that can realize the protection function.
In actual work, due to the needs of operation and maintenance personnel to stop, power transmission operation or maintenance personnel to debug the protection device and adjust the operation mode of the primary system, it is necessary to quickly adjust and change the operation status of the secondary pressure plate of the protection device to realize the primary operation equipment under a specific operation mode. Therefore, the existing monitoring of the operating status of the protection device cannot achieve effective monitoring of the protection device
[0005] The monitoring personnel on duty cannot compare the changes in the operation mode of the primary equipment, and promptly remind the personnel on duty of the substation to adjust the switching and stopping of the secondary pressure plate of the on-site relay protection device of each substation, resulting in protection misoperation due to leakage of the secondary pressure plate. , Refusal to operate causes artificial expansio

Embodiment 1

[0056]Embodiment 1: The secondary pressure plate forced locking device according to the present invention includes a casing, and also includes the following components: upper casing 1, lower casing 2, static contact ferrule 3, internal rotating shaft 4 of ferrule, and locking sleeve The left half of the base 5, the internal lock 6 and the RFID chip 7, the upper shell 1 is provided with the moving contact lock sleeve 8, the rotation track groove guard plate 9, the RFID chip installation groove 10 and the groove 11, the rotation track groove Guard plate 9 is located in moving contact lock sleeve 8, and is fixedly connected, and RFID code chip installation groove 10 side is provided with keyhole 15; Both lower shell 2 and upper shell 1 are provided with screw holes, and are connected by bolts. The upper shell 1 and the lower shell 2 are fixedly connected in the screw hole, and the lower shell 2 is provided with a groove B12 corresponding to the groove 11 of the upper shell 1, and ...

Embodiment 2

[0057] Embodiment 2: On the basis of the structure described in Embodiment 1, the static contact ferrule moving groove 13 includes a slider sliding track and a connecting block sliding track, the section of the slider sliding track is adapted to the slider section, and the connecting block sliding track The cross-section is less than the cross-section of the slide block, so that the slide block 18 can only move in the slide block sliding track, but cannot pass the connecting block sliding track.

Embodiment 3

[0058] Embodiment 3: On the basis of the structure described in Embodiment 2, the locking sleeve clamping base 27 is set on the moving contact base of the pressure plate, the moving contact lock sleeve 8 is set on the moving contact of the pressure plate, and the pressure plate connecting piece Pass through the slot 26 of the connecting piece.

Abstract

The invention provides a method for monitoring a secondary pressure plate compulsory locking device and the state thereof, and belongs to the field of apparatuses for monitoring the states of put-into-use and out-of-use of secondary pressure plate of an electric power system. The invention involves the secondary pressure plate compulsory locking device, a scheduling main station server, an anti-error host and a computer key. A pressure plate can be compulsorily locked, and completely broken apart, and the states of put-into-use and out-of-use of the pressure plate are effectively recorded. The secondary pressure plate compulsory locking device can be installed while a secondary pressure plate is under an operating state, and on-line monitoring the states of put-into-use and out-of-use of relay protective pressure plate of all stations at the scheduling main station can be realized through telecommunication.

Description

technical field [0001] The invention provides a forced locking device for a secondary pressing plate and a state monitoring method thereof, and belongs to the field of monitoring devices for switching on and off of a secondary pressing plate in a power system. Background technique [0002] The secondary equipment of the power system is an important part of the safe operation of the power grid. It monitors, measures, operates and controls the primary equipment and plays a protective role. The relay protection device in the secondary equipment is an important guarantee for the safe and stable operation of the primary equipment in the power grid. Among the existing protection devices, the secondary pressure plate is used to switch on and off the function of the protection device and the key to the trip outlet circuit. The pressure plate is correctly put in, Whether to exit or not is directly related to whether the protection device can operate correctly, and the fault can be re...
