Abstract
The utility model discloses a relay protection pressure plate voice signal alarming device, and aims at solving the problem that in practical operation, a protective device can not carry out correct action because of the improper inputting and withdrawing of a pressure plate, and operating personnel have no way of knowing the situation. The relay protection pressure plate voice signal alarming device comprises a pressure plate contact (1), a voice and signal lamp module (2), and a power supply (3). The pressure plate contact (1) is electrically connected to the power supply (3) through the voice and signal lamp module (2). The relay protection pressure plate voice signal alarming device of the utility model provides great convenience for the operation of the working personnel, simplifies the working procedures, and improves the working efficiency.
Description
Technical field
The utility model is related to a kind of warning device, the warning device of the protection pressing plate of more particularly to a kind of protective relaying device.
Background technology
The protection pressing plate of protective relaying device is also named protection in flakes, is the bridge and tie of protection device contact external wiring, and can the function and action outlet that be related to protection normally play a role.Because of the particularity of relay protection trip pressing plate, under normal condition（Without trip signal）When, both sides can not be simultaneously powered.And the throwing of pressing plate is moved back by manually operating, sense of responsibility, actual techniques level completely by operations staff are checked on.Therefore in actual motion, thrown because of pressing plate and move back improper, the phenomenon for causing protection system to be unable to correct behavior happens occasionally.
The content of the invention
The utility model provides a kind of relay-protection pressing plate voice signal warning device, solves in actual motion, because pressing plate throw move back it is improper caused by protection device be unable to correct operation and operating personnel can not know the problem of.
The utility model is to solve above technical problem by the following technical programs：
A kind of relay-protection pressing plate voice signal warning device, including pressing plate contact, voice and signal lamp module and power supply, pressing plate contact（1）Linked together by voice and signal lamp module with power supply.Pressing plate closure rear indicator light is bright, while junction closure, carries out voice message when pressing plate disconnects, illustrate that pressing plate has been connected, plays a part of pointing out operation maintenance personnel.
The utility model greatly facilitates the operation of the personnel of work, simplifies workflow, improves operating efficiency.
