Description

technical field [0001] The invention relates to the technical field of relays, in particular to a high-voltage ignition relay and an operating method thereof. Background technique [0002] As a key component related to the safety and reliability of the weapon system, the ignition device directly affects the survivability and combat effectiveness of the entire weapon system. Under various harsh environmental conditions, on the one hand, it is required to ensure that the rated current pulse (generally working voltage is DC 27V) is provided to the ignition element (pyrotechnics) in a combat state; on the other hand, it is required to be in a safe (non-combat) state , to prevent ignition components from misignition under the action of radio frequency and static electricity. At present, the traditional pyrotechnic ignition circuit of the weapon system uses low voltage (DC 27V) and small current (10A) to ignite. Since the traditional pyrotechnic ignition circuit uses an electrome...

Problems solved by technology

At present, the traditional pyrotechnic ignition circuit of the weapon system uses low voltage (DC 27V) and small current (10A) to ignite. Since the traditional pyrotechnic ignition circuit uses an electromechanical isolation safety device to isolate the insensitive ignition element, it will be even worse in the future. There are unsafe factors in both the electromagnetic environment and the mechanical environment

However, the existing high-pressure ignition systems and schemes are mainly aimed at oil, combustible gases, solids and powders for combustion ignition control, which do not meet the requirements for explosion ignition of high-pressure pyrotechnics in weapon systems, and do not have reliable insurance mechanisms, which do not meet the requirements of weapon systems.
