Abstract

The invention discloses a large power emergency power source static discharge control panel protection circuit. The large power emergency power source static discharge control panel protection circuit comprises a charger, a first diode, a second diode, a control panel, a storage cell, an intermediate relay and a solenoid thereof, a forced turn button, a first switch power source and a second switch power source, wherein the charger is connected with the control panel through the first diode and the second switch power source, the charger is separately connected with the storage cell and the intermediate relay through the second diode, the intermediate relay is connected with the second switch power source, a positive electrode of the storage cell outputs two paths, one path passes through the first switch power source, a relay on the control panel and the solenoid of the intermediate relay and is connected with a negative electrode of the storage cell, and the other path is directly connected with a cathode of the second diode. According to the large power emergency power source static discharge control panel protection circuit, a 500V dc current of the storage cell is converted into a 20V dc current through the switch power source, not only can the protection effect on the relay on the control panel be realized, but also properties of simple line, convenient use and low cost are realized.

Description

technical field [0001] The invention belongs to the field of electricity and relates to an emergency power supply, in particular to a protection circuit for a static discharge control board of a high-power emergency power supply. Background technique [0002] The emergency power supply includes chargers, inverters, batteries, isolation transformers, and switches. It is a device that converts DC power into AC power. When the mains fails or a fire occurs, the battery is converted into AC power through the inverter. , and then through the isolation transformer to provide power for the emergency lighting indicators, so that personnel can escape the fire scene safely. [0003] When the emergency power supply is working in an emergency, the battery releases electricity to provide electric energy for the emergency equipment. The voltage of the battery is determined by the emergency time and emergency power. Generally, the high-power emergency power supply requires a high DC voltage...
