Embodiment A

[0022] The invention provides an on-board measurement and control circuit of the SSPC channel of the solid-state power distribution device. The SSPC channel of the solid-state power distribution device is connected in series with the load. In case of false tripping, the on-board measurement and control circuit can ensure the normal use of the load originally controlled and protected by the SSPC channel, and the load line protection function will not be lost. The on-board measurement and control circuit includes circuit breaker A, reset switch K1, alarm module and reset module;

[0023] The input of circuit breaker A comes from the same bus bar as the input of SSPC channel, the output terminal of circuit breaker A is connected with the input terminal of reset switch K1, and the output terminal of circuit breaker A is also connected with the alarm module;

[0024] The output end of the reset switch K1 is connected to the reset module, and is used to control the power-on and power...

Embodiment B

[0030] Such as figure 1 As shown, the present invention also provides an on-board measurement and control circuit for the SSPC channel of a solid-state power distribution device. The on-board measurement and control circuit in this embodiment is based on the on-board measurement and control circuit in Embodiment A, wherein:

[0031] The reset module is relay A, and the alarm module includes relay B, alarm lamp and buzzer;

[0032] The coil A input terminal of the relay A is connected to the output terminal of the reset switch, and the two ends of the normally open contact A of the relay A are respectively connected to the bus bar and the load. When the reset switch is connected, the coil A is energized, causing the normally open contact A to be connected. The load is energized;

[0033] The coil B input terminal of relay B is connected to the output terminal of normally open contact A and the load, and the normally closed contact B of relay B is connected to circuit breaker A...

Abstract

The invention relates to the technical field of aircraft power distribution, a measurement and control circuit for SSPC channel of solid-state power distribution device is provided in detail, Circuitbreakers, relays, and switches are used to take over the load when the SSPC channel trips incorrectly. Relays, indicators, and buzzers are used to indicate when the SSPC channel erroneously trips. Themeasurement and control circuit can send instructions to the crew through sound and light when the SSPC in the solid-state power distribution device trips by mistake, and the crew can carry out loaddistribution and line protection through the electromechanical circuit breaker in the circuit, thus ensuring the normal operation of the aircraft system in which the load is located.

Description

technical field [0001] The invention relates to the technical field of aircraft power distribution, in particular to an on-board measurement and control circuit of an SSPC channel of a solid-state power distribution device. Background technique [0002] The solid-state power distribution device is a power distribution device based on solid-state power distribution technology and computer integrated control technology. A solid-state power distribution device is mainly composed of a processor module, a signal conditioning module, and multiple solid-state power controller (SSPC) channels. The SSPC channel inside the solid-state power distribution device has the functions of connecting load power supply, disconnecting load power supply, overload protection, and short circuit protection. [0003] On an aircraft, common solid-state power distribution device SSPC channels use circuits such as figure 1 shown. Electric energy is transferred from the bus bar to the SSPC channel in ...
