Abstract

The invention provides an activating circuit for a high-voltage thermal battery unit of a servo power supply, belonging to the electromechanical field. According to the activating circuit, the problems that an existing high-voltage thermal battery unit is long in activation time and low in reliability are solved. The activating circuit comprises a first activating loop, a redundancy activating loop and an activating signal generating circuit, wherein the activating signal generating circuit is used for outputting impulse voltage signals; the first activating loop comprises a first electromagnetic relay and a second electromagnetic relay which are normally open relays; one ends of three switches of the first electromagnetic relay are connected with one ends of three switches in the second electromagnetic relay through a first activating bridge of the high-voltage thermal battery unit in a to-be-activated servo power supply, the other ends of the three switches in the first electromagnetic relay are simultaneously connected with an output positive electrode of the activating signal generating circuit, and the other ends of the three switches in the second electromagnetic relay are simultaneously connected with an output negative electrode of the activating signal generating circuit. According to the scheme, the high-voltage thermal battery unit is short in activation time and high in reliability.

Description

technical field [0001] The invention relates to the electromechanical field, in particular to an activation circuit for a high-voltage thermal battery unit of a servo power supply. Background technique [0002] Servo system is the collective name of the closed-loop system for the flight control of launch vehicles in my country. One of its typical applications is to complete the thrust vector control of the engine on solid launch vehicles. Due to its inherent advantages of simple composition and structure, convenient use and maintenance, and long storage period, the electromechanical servo system has gradually become the mainstream application and development direction of thrust vector control for solid launch vehicles. [0003] The electromechanical servo system is mainly composed of the following parts: electromechanical actuator, servo control driver, servo power supply and system cable network. Among them, the servo power supply provides DC power for the entire electrome...
