Description

Technical Field

[0001] The utility model relates to the technical field of pressure plates, in particular to a relay protection pressure plate with a state detection structure. Background Art

[0002] The relay protection pressure plate in the electrical equipment is used to connect or disconnect the control circuit of the relay protection device. The correct input and output of the pressure plate is an important guarantee to ensure the safe operation of the relay protection system. The input and output of the pressure plate are operated manually;

[0003] The existing publication number CN218444228U discloses a relay protection pressure plate with a state detection structure, including a pressure plate assembly, a detection assembly and a state indicating device. When the connecting piece connects the base a and the base b, the pressure sensor converts the pressure received by the connecting plate into an electrical signal in real time and sends it to the controller. When the electrical signal output by the pressure sensor does not reach the threshold, the controller turns on the lamp bead. If the controller detects that the electrical signal output by the pressure sensor reaches the threshold, the controller turns off the lamp bead. The operator can understand the state of the relay protection pressure plate by checking the on and off of the lamp bead, avoiding the problem of electrical equipment failure during operation due to poor contact caused by the connector not being pressed tightly.

[0004] However, when the existing relay protection pressure plate is put into operation or withdrawn, the threaded cap used to tighten the connecting piece needs to be removed, the connecting piece is then put on or removed, and then the threaded cap is installed and tightened. It cannot be directly put into operation or withdrawn, which makes the operation very cumbersome and time-consuming. In addition, the connection status of the pressure plate cannot be intuitively understood through the current status, but is judged by the pressure status of the connecting piece, resulting in inaccurate detection results.
