Embodiment Construction

[0024] Such as Figure 1 to Figure 8 As shown, the relay protection hard-press plate anti-misoperation operating system includes a hard-press-plate state setting module, a hard-press-plate state sampling module, a hard-press-plate state comparison module, and an anti-misoperation alarm module. Set the state of each hard press plate, the hard press plate state sampling module obtains the working state of the hard press plate by collecting the voltage at the contact point of each hard press plate, and the hard press plate state comparison module compares the working state of each hard press plate with the set state For comparison, the anti-misoperation alarm module sends a corresponding misoperation alarm according to the comparison result of the hard platen state comparison module.

[0025] Such as figure 1 As shown, the operator selects the corresponding protective device screen in the computer according to the dispatch order, and sets the state of the hard pressure plate in ...

Abstract

The invention discloses a relay protection hard pressure plate anti-misoperation system comprising a hard pressure plate state setting module, a hard pressure plate state acquiring module, a hard pressure plate state comparing module, and an anti-misoperation alarm module. The hard pressure plate state setting module sets the states of various hard pressure plates according to a scheduling command. The hard pressure plate state acquiring module acquires the operating states of the hard pressure plates by acquiring the voltage at the contacts of the hard pressure plates. The hard pressure plate state comparing module compares the operating states of the hard pressure plates with set states. The anti-misoperation alarm module correspondingly gives a maloperation alarm according to a comparison result of the hard pressure plate state comparing module. The relay protection hard pressure plate anti-misoperation system solves maloperation phenomena frequently appearing in hard operation processes.

Description

technical field [0001] The invention relates to a relay protection technology, in particular to a relay protection hard pressing board anti-misoperation technology. Background technique [0002] The relay protection hard press is an important part of the relay protection device, and its opening and closing state is directly related to whether the protection automation device can operate correctly. At present, the operation of the hard pressing plate of the relay protection device in the substation is carried out by the operator according to the dispatch order. However, because some protection devices have a large number of hard pressure plates, for example, the number of hard pressure plates on the screen of the main transformer protection device may be as many as 20, so the problem of hard pressure plate misoperation often occurs. However, most of the power supply companies in our country currently adopt the method of manual review for this problem, that is, after the oper...
