Security and protection system pressure regulating device no-load pressure regulating electron outage method

Abstract

Provided is a security and protection system pressure regulating device no-load pressure regulating electron outage method. Through a no-load pressure regulating outage indicator of an upper computer with a prompt no-load pressure regulating outage indicator, a no-load pressure regulating mode is selected, then no-load pressure regulating commands are sent to a programmable logic controller, the programmable logic controller transmits and judges a state of a security and protection system pressure regulating device master control switch relay protector through a security and protection system pressure regulating device discrete magnitude input module, and if the state of the security and protection system pressure regulating device master control switch relay protector is an open state, discrete magnitude is called for activating an output module to carry out closing operation. Finally, automatic outage before no-load pressure regulating can be achieved, and the consequence that a pressure regulating device is damaged so as to cause casualties easily can be avoided.

Description

technical field [0001] The invention relates to the field of security technology, in particular to an electronic power-off method for off-load voltage regulation of a security system voltage regulation device. Background technique [0002] In the voltage regulation equipment of the security system, the no-load voltage regulation method is often used. The split voltage can only be adjusted after a power failure, which is called no-load voltage regulation. The function of the voltage regulation device is that when the grid voltage changes and the load changes, it will cause fluctuations in output voltage. If the voltage is too high or too low, it will affect the normal operation of the point-of-use equipment. The voltage regulating equipment is to ensure that the grid voltage changes within a reasonable range, but it often occurs that the operator forgets to power off and then performs no-load voltage regulation, which leads to damage to the voltage regulating equipment and e...
