Embodiment Construction

[0013] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0014] like figure 1 The trip protection device of the present invention shown includes a protection circuit and an indicating device. The protection circuit, the protection circuit includes a protection device 1 used to detect the information that needs to trip and send a trigger pulse after detecting the information that needs to trip, a protection pressure plate 2 used to control the on-off of the protection circuit and receive the trigger pulse of the protection device 1 After disconnecting the trip coil 3, the protection device 1, the protection pressure plate 2 and the trip coil 3 are connected in series. An indicating device, one end of the indicating device is connected between the pr...

Abstract

The invention provides a trip protection device which comprises a protection loop and an indicating device. The protection loop comprises a protector, a protection pressing plate and a trip coil, wherein the protector is used for detecting the information that trip is needed and sending a trigger pulse after detecting the information that trip is needed, the protection pressing plate is used for controlling the protection loop to be closed and opened, and the trip coil is disconnected after receiving the trigger pulse of the protector. The protector, the protection pressing plate and the trip coil are connected in series. One end of the indicating device is connected between the protector and the protection pressing plate. The trip coil, the protection pressing plate and the indicating device form a series loop. By applying the technical scheme, the indicating device reflects the state of the protection pressing plate, and whether the protection pressing plate is put in or exits can be clearly judged.

Description

technical field [0001] The present invention relates to the field of relay protection, more specifically, to a trip protection device. Background technique [0002] The protection pressure plate is also called the protection connecting piece. It is the bridge and link for the protection device to connect to the external wiring. It is very important for the function of the protection and whether the action outlet can work normally. At present, the operating personnel cannot distinguish the switching status of the pressure plate, and the identification method of input and exit is to measure the potential with a digital multimeter, which is very inconvenient to identify. Contents of the invention [0003] The invention aims to provide a trip protection device which can clearly judge whether the protection pressing plate is put into or out of. [0004] In order to achieve the above object, the present invention provides a trip protection device, the trip protection device inc...
