Embodiment Construction

[0022] As mentioned in the background technology section, in the prior art, the state of the pressure plate is basically judged by the position of the handle on the appearance. The state of the pressure plate and its throw-in and withdrawal time need to be recorded manually, which has low accuracy, heavy workload, and low efficiency. high cost.

[0023] Based on this, an embodiment of the present invention provides a pressure plate state detection device, including:

[0024] A sensor component, the sensor component is installed on the substrate of the detected pressure plate, including a circuit board, the circuit board is provided with a photoelectric emitting element for emitting an optical signal, and the circuit board is provided with a photoelectric receiving element for receiving an optical signal, According to the state of the photoelectric receiving element, the circuit board outputs the corresponding state signal of the detected pressure plate and the throwing and wit...

Abstract

The invention discloses a pressing plate state detection device. The pressing plate state detection device comprises a sensor component and a shielding component, wherein the sensor component is installed on a substrate of a detected pressing plate and comprises a circuit board, the circuit board is provided with a photoemissive element used for emitting optical signals, the circuit board is provided with a photoelectric receiving element used for receiving photoelectric signals, and the circuit board outputs corresponding state signals and the time of feed back to volt of the detected pressing plate according to the state of the photoelectric receiving element; a first end of the shielding component is fixedly connected with a handle of the detected pressing plate, the shielding component moves along with the handle of the detected pressing plate, a second end of the shielding component moves between the photoemissive element and the photoelectric receiving element and changes the light path connecting and disconnecting state of the photoemissive element and the photoelectric receiving element. The pressing plate state detection device can obtain the state and the time of feed back to volt of the detected pressing plate in real time, is high in accuracy, light in workload, high in efficiency and free of any hidden risks in the modification process.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a pressure plate state detection device. Background technique [0002] In power equipment, a protective pressure plate, also known as a connecting piece, is usually designed on the relay protection circuit, including a protective function pressure plate and an outlet pressure plate. The protection function pressure plate realizes some functions of the protection device (such as main protection, distance protection, zero Sequence protection, etc.); the outlet pressure plate determines the result of the protection action. According to the different objects of the protection action outlet, it can be divided into a trip outlet pressure plate and a start pressure plate. As an important secondary equipment, the pressure plate is still at a relatively low level of intelligence. [0003] At present, the pressure plate in the power system, the pressure plate includes the base plate and ...
