Problems solved by technology
The indirect methods currently appearing rely on electromagnetic or photoelectric signals to judge the throwing and withdrawing status of the pressure plate, but all of them add a relatively complicated external judgment part, which is easily affected by the use environment (such as electromagnetic interference) and cause misjudgment, and other The external judgment part added by itself is prone to failure and misjudgment in actual use, so the reliability is low, and the operation and maintenance cost of the equipment is also increased.

The embodiment of the present application discloses a double outlet pressure plate, comprising: a pressure plate base; a first pressure plate and a second pressure plate for transmitting the position signal information of the first pressure plate to the relay protection device are arranged at intervals on the pressure plate base pressing plate; the first pressing plate includes a first upper terminal and a first lower terminal; the second pressing plate includes a second upper terminal and a second lower terminal; the first upper terminal and the first lower terminal pass through the first connecting piece The second upper connecting post and the second lower connecting post are connected by a second connecting piece; the first connecting piece and the second connecting piece are connected by a fixing seat; the fixing seat is provided with a throwing and retreating component for realizing the simultaneous connection of the dual circuits. The present invention can achieve the purpose of synchronously throwing and withdrawing the first pressing plate and the second pressing plate, and indirectly knowing the throwing and withdrawing state of the other pressing plate through the throwing and withdrawing state of one pressing plate.
Description
technical field [0001] The present application relates to the technical field of relay protection and safety automatic devices in power systems, in particular to a double outlet pressure plate. Background technique [0002] With the continuous development of the power grid, the safe operation of the power grid is particularly important. Relay protection and safety automatic devices in the power system are important equipment in the safe operation of the power grid, providing protection for the safe and stable operation of the power system. The switching of the pressure plate (also known as "connected piece") in this type of equipment is the main item in the operation of the equipment. The pressure plate is used to connect or disconnect a certain circuit, and it is the relay protection and safety automatic device to contact the external or internal The bridges and ties of the wiring are related to the protection function of the equipment and whether the action outlet can fun...
