Energy-saving boost relay

Abstract

The invention discloses an energy-saving booster relay, A front stage of the isolated power module is electrically connected to a DC input power supply. A step-up circuit module is arrange in front ofthat coil driving indication circuit module, A low stage of that boost circuit module is electrically connected to the high voltage relay coil, A step-up circuit module front stage is electrically connected with a step-down circuit module and a logic judgment and instruction transmission circuit module respectively, A step-down circuit module is electrically connected with a DC input power supplyand a logic judgment and instruction transmission circuit module respectively, and when that logic judgment and instruction transmission circuit module judge to obtain a high-voltage relay on signal,the step-up circuit module is conveyed to control the boosting instantaneous voltage; A step-down circuit module, a step-up circuit module, a logic judgment and instruction transmission circuit module, and a coil driving instruction circuit module are integrate into that relay to form an integral relay structure, and the step-down circuit module, the step-up circuit module, the logic judgment andinstruction transmission circuit module, and the coil driving instruction circuit module are integrated into the relay. The utility model improves the service reliability and service life of the high-voltage relay, reduces energy consumption and waste, and has low total energy consumption.

Description

technical field [0001] The invention relates to a relay, in particular to an energy-saving booster relay capable of detecting the on-off information status of a high-voltage contact of the high-voltage relay. Background technique [0002] Usually, high-voltage relays are used in equipment that requires random monitoring and remote monitoring, such as electric vehicles and charging piles. The power of the driving coil of the high-voltage relays currently used in these devices is usually designed to meet the pull-in time of the relay. On the power demand index, and most of the time, the relay works in the period of maintaining pull-in. The power requirement for maintaining the pull-in period is usually less than 0.4 times the power requirement for the pull-in period. However, the existing high-voltage relays are always running according to the power design requirements of the pull-in time period, resulting in waste of power, high total energy consumption, and it is not conduc...
