Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0026] Such as figure 2 As shown, a verification device of a UHV station circuit breaker synchronous control device according to the present invention mainly includes a measurement and control device, a synchronous / asynchronous switching selection switch, a relay protection three-phase tester, a circuit breaker synchronous control device, and a fault recorder devices, low-resistance circuit breakers and secondary circuits. Wherein, the measurement and control device includes a measurement and control screen.

[0027] The relay protection three-phase tester is used to provide the three-phase positive-sequence current and reference voltage required for the calibration test. The three-phase positive-sequence current is connected to the low-resistance circuit breaker in series after passing through the circuit breaker synchronous control device and the fault recorder, s...

Abstract

The invention discloses a verification device for a breaker synchronous control device of an extra-high pressure station. The verification device comprises a measurement control device, a synchronous / asynchronous switching selection switch, a relay protection three-phase tester, the breaker synchronous control device, a fault recorder, a low-resistance breaker and a secondary circuit. The invention further provides a verification method of the verification device. According to the verification device and the verification method, an experimental model is established at the scene and a corresponding operation method is executed, so that the debugging and acceptance inspection of the breaker synchronous control device are completed, and the difficulty of debugging and acceptance-inspecting the breaker synchronous control device at the scene is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of UHV power transmission and distribution, and in particular relates to a verification device and a verification method for a synchronous control device of a circuit breaker in an UHV station. Background technique [0002] Such as figure 1 As shown, the low-voltage side of the main transformer of the existing UHV station is usually equipped with a set of parallel reactors 1112L. The reactors 1112L are connected in star form, and each phase is composed of two reactors connected in series to make up for the lack of capacity. Among them, the low-resistance circuit breaker 1112 adopts a phase-splitting operating mechanism. [0003] Due to the need to maintain reactive power balance and suppress bus voltage rise at light loads, it is necessary to perform group switching of low-resistance (low-voltage side reactors) through background remote control of low-resistance circuit breakers. In actual operation, group ...
