Abstract

The invention discloses a power distribution self holding circuit applied to missile-borne equipment and achieves self holding or cutting of power supply signals of the missile-borne equipment based on control instructions. The power distribution self holding circuit comprises electromagnetic relays K1-K6, and each relay comprises two groups of normally-opened contacts and two groups of normally-closed contacts. A network cutting control signal is connected with positive ends of solenoids B5 and B6, and negative ends of solenoids B1-B6 are connected to a power supply negative signal. A main power supply negative signal and the power supply negative signal are connected to a bus bar negative signal. Common ends COM5-1, COM5-2, COM6-1 and COM6-2 are short connected and then are connected with a grid connected control signal and the positive ends of the solenoids B3 and B4. Normally-closed contacts K5-1, K5-2, K6-1 and K6-2 and normally-opened contacts K3-1, K3-2, K4-1 and K4-2 are short connected and then are connected with the positive ends of the solenoids B1 and B2. Common ends COM1-1, COM1-2, COM2-1 and COM2-2 are short connected and then are connected with a power supply positive signal and a bus bar positive signal. Normally-opened contacts K1-1, K1-2, K2-1 and K2-2 are short circuited and then are connected to a main power supply positive signal. Common ends COM3-1, COM3-2, COM4-1 and COM4-2 are short connected and then are connected with the main power supply positive signal.

Description

technical field [0001] The invention belongs to the technical field of launch control, and in particular relates to a power distribution self-protection circuit applied to missile equipment. Background technique [0002] With the rapid development of electronic technology, the integration of analog-to-digital circuits is increasing day by day, the technical strength and functions of missile-borne equipment are increasing day by day, and the complexity is also getting higher and higher. There must be sufficient energy provided to each equipment on the missile for perform their respective functions. Generally, before the missile is launched, the ground test equipment or the pre-launch control equipment shall apply the ground power supply to provide working power for the equipment on the missile; after the missile is launched, the main power supply on the missile shall provide working power for the equipment on the missile. The main power supply, also known as the primary powe...
