Isolated power supply output circuit with self-protection function

Abstract

The invention relates to an isolated power supply output circuit with a self-protection function. The circuit is characterized in that four kinds of 27V electricity are defined as follows, F27V, M27V,G27V and A27V; F27V is a launch control 27V, and F27V or F27VG is adopted by a switching value instruction and a signal which are connected with a control circuit of a Wu control device; G27V is isolation 27V, and G27V or G27VG is adopted for bullet type identification signals, bullet type identification loop lines, insurance instructions and insurance control; an A27V safety mechanism adopts 27V, and a fighting state signal and an insurance state signal adopt A27V or A27VG; M27V is weapon 27V electricity, and the weapon 27V electricity becomes a stable 28V input relay control panel after being isolated by an isolation power supply. The circuit is advantaged in that the self-protection function of weapons can be effectively achieved.

Description

technical field [0001] The invention relates to a power supply output circuit, in particular to an isolated power supply output circuit with self-protection function. Background technique [0002] When supplying power to underwater weapon equipment, the watertight cable at the tail of the weapon is soaked in seawater after the weapon is launched, causing a potential loop in the corresponding position of the weapon control equipment, resulting in abnormal lighting of the status indicator light of the weapon control equipment after the weapon is launched out of the tube, or If there is a wrong loading information prompt, it is necessary to redesign the isolated power supply output circuit in the weapon control equipment. Contents of the invention [0003] The purpose of the present invention is to design an isolated power supply output circuit with self-protection function, which is used to solve the above-mentioned problems in the prior art. [0004] The present invention ...
