Abstract

The invention relates to a switching device for power supply or power distribution, and discloses a surge suppressor of a switch for power supply and distribution of low-power equipment. The surge suppressor is characterized in that resistors R1 and R3 are connected in parallel; one end of the resistors is connected with the grid of an MOS (metal-oxide-semiconductor) field-effect transistor Q1, and the other end of the resistors is connected with the source of the Q1 and the positive end of a direct-current power supply; resistors R2 and R4 are connected in parallel and are connected between the grid of the Q1 and the negative end of the direct-current power supply in series; capacitors C1 and C2 are connected between the grid and source of the Q1 in series; and the drain of the Q1 is connected with power supply filtering or loading equipment by a fuse. The invention also discloses a surge suppressor of a switch for power supply and distribution of high-power equipment. The surge suppressors solve the problem of electromagnetic compatibility of on/off power equipment of complex systems and achieve the beneficial effects of simple circuit, convenience in debugging, obvious surge suppression, low cost, high reliability and the like.

Description

technical field [0001] The present invention relates to a switchgear for power supply or power distribution, in particular to a surge suppressing device such as a switch for power supply or power distribution of an aerospace vehicle electronic equipment system. Background technique [0002] Modern electronic, electrical, electromechanical equipment, especially aerospace vehicle electronic equipment systems are becoming more and more complex. For a complex electronic system, it usually refers to a collection of multiple electronic equipment, electrical equipment and electromechanical equipment, which are co-located in a limited space, and there is space electromagnetic field coupling between them, and there may also be interconnected electrical conductors Conducted electromagnetic coupling. The DC power supply and distribution for these various "large / small" power devices, and the implementation of "on / off" operations are the basic requirements for the task realization and p...
