Abstract
Provided is a load-free early warning device for a security and protection system voltage regulating apparatus. Through adoption of a main power supply system for the security and protection system voltage regulating apparatus, a electromagnetic communication central station main control switch, a moving contact of a relay protection system of the switch and a moving contact on and off discrete magnitude input module are in communication and conduction, and a control pin of the load-free voltage regulating early warning device is in communication and conduction with a voice early warning system. Through introduction of the above early warning technology, a phenomenon that an operation worker forgets to cut off the power to regulate voltages under a load-free condition is substantially minimized.
Description
Technical field
The utility model relates to technical field of security and protection, particularly a kind of safety-protection system voltage adjusting device No-load changer prior-warning device.
Background technology
In the safety-protection system voltage adjusting device, what often adopt is the No-load changer mode, could adjust the separately title No-load changer of voltage after needing to have a power failure, and the effect of voltage adjusting device is when the variation of line voltage and the variation of load, can cause the fluctuation of output voltage.Voltage is too high or too low to work the meeting impact with point device.Voltage adjusting device is exactly in order to guarantee that line voltage changes in the reasonable scope, forgets that power failure just carries out No-load changer but operating personnel often occur, has so just caused the damage voltage adjusting device and has very easily caused personnel casualty accidents.
Summary of the invention
The utility model provides a kind of safety-protection system voltage adjusting device No-load changer prior-warning device; via arranging via safety-protection system voltage adjusting device main power supply system moving contact and the moving contact folding discrete magnitude load module communication conducting of electromagnetic communication central station master switch with its relay protection system, and the control pin of No-load changer prior-warning device and phonetic warning system communication conducting.Having introduced such early warning technology can greatly reduce operating personnel and forget that power failure just carries out the phenomenon of No-load changer.
For achieving the above object, the technical solution of the utility model is:
A kind of safety-protection system voltage adjusting device No-load changer prior-warning device; setting via safety-protection system voltage adjusting device main power supply system 6 electromagnetic communication central station master switch 3 with the moving contact 5 of its relay protection system and the 4 communication conductings of moving contact folding discrete magnitude load module, and the control pin 1 of No-load changer prior-warning device 7 and the 2 communication conductings of phonetic warning system.
Via arranging via safety-protection system voltage adjusting device main power supply system 6 moving contact 5 and the moving contact folding discrete magnitude load module 4 communication conductings of electromagnetic communication central station master switch 3 with its relay protection system, and the control pin 1 of No-load changer prior-warning device 7 and the 2 communication conductings of phonetic warning system.Having introduced such early warning technology can greatly reduce operating personnel and forget that power failure just carries out the phenomenon of No-load changer.
