Embodiment Construction
[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the device for detecting the throwing and withdrawing status of the contiguous protective platen and the protective platen with it of the present invention will be further described in detail through the following examples and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0034] In the description of the present invention, the terms "first" and "second" are used for description purposes only, and cannot be understood as indicating or implying relative importance.
[0035] At present, more connected protective pressure plates are used in power systems, including a pressure plate seat and a pressure plate state change mechanism connected to the pressure plate seat. The pressure plate state change mechanism includes a connec...

The invention provides a contiguous protective switch on-off state detection device. The detection device comprises a mounting component and a detection component; the mounting component comprises a fixed part fixed at a switch state change mechanism, the fixed part comprises a platy bracket on which a through hole is formed; an elastic card is arranged on one surface of the platy bracket to surround the through hole; the detection component is used for detecting a location of the switch state change mechanism. The contiguous protective switch on-off state detection device and the protective switch with the same comprise the mounting component and the detection component, the detection device can be directly loaded on the switch state change mechanism of the protective switch through the fixed part of the mounting component, for instance, the detection can be loaded on a handle sleeved on the protective switch, the shape of the handle is unlimited and can be square or round, the reformon the original protective switch is unnecessary; the detection device can be compatible with the contiguous protective switches in various shapes, and the mounting and use are convenient.
Description
technical field [0001] The invention relates to the field of electric equipment, in particular to a device for detecting the throwing and withdrawing state of a contiguous protective pressing plate and a protective pressing plate with the same. Background technique [0002] The protection pressure plate is a very important power secondary equipment. It is generally installed in the circuit of the power relay protection equipment. The correct switching of the protection pressure plate is an important guarantee for the normal operation of the relay protection equipment. cause huge losses. The intelligent protection pressure plate equipment is widely used in power systems by detecting the switching status of the pressure plate and alarming the error state. [0003] The existing intelligent protection platen equipment is mainly realized in the following two ways. The first is to design a brand-new intelligent protection platen equipment, so that the sensors, signal acquisition...
