Problems solved by technology

However, traditional fuses are generally irreversible to equipment due to their overcurrent protection methods, and have disadvantages such as wide fusing range, long fusing time, and large impact on current equipment.
In addition, the traditional relay has the disadvantages of limited switching times, electric shock is easy to arc and spark under the action of high voltage, and it is easy to trigger misoperation under the mechanical environment.

Abstract

The invention discloses a space solid state power distribution protection circuit, method and a power supply and distribution system. An auxiliary power supply module outputs a first voltage to an on / off control module and outputs a second voltage to an overcurrent / short circuit protection module, and the on / off control module controls on and off of the space solid state power distribution protection circuit through a command mode; a driving module amplifies on and off signals of the command mode and drives on and off of a switch module; and a current sampling module acquires a bus voltage ofa bus power supply and performs real-time monitoring, and when the bus voltage is greater than a first preset threshold voltage, the overcurrent / short circuit protection module quickly cuts off the switch of the switch module. The advantages of fast action response and high reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of power supply and distribution, in particular to a space solid-state power distribution protection circuit, method and power supply and distribution system. Background technique [0002] In the field of power supply and distribution technology, the protection circuit design of the power supply and distribution system is a very important technology. It can ensure that the input voltage of the power supply and distribution system is too large to prevent permanent damage to the equipment and reduce maintenance costs. However, traditional fuses are generally irreversible to equipment due to their overcurrent protection methods, and have disadvantages such as wide fusing range, long fusing time, and large impact on current equipment. In addition, traditional relays have disadvantages such as limited switching times, easy arcing and ignition under high voltage, and easy triggering of malfunctions under mechanic...
