Problems solved by technology

[0004] After the electric ignition head of the gas generator is ignited, due to the conductivity of the gunpowder residue or the internal bridge wire of the ignition head is fused and connected to the metal shell of the gas generator, resulting in gas generation There is a small resistance or even a complete short circuit between the input terminals of the device
After the user activates the reserve battery, if the DC power supply is not disconnected, the DC power supply will be in a state of high current output or short circuit, resulting in failure

Abstract

The invention discloses a control circuit and a control method for an activation circuit resistor of a zinc-silver reserve battery, and belongs to the technical field of zinc-silver reserve batteries.The control circuit for the activation circuit resistor of the zinc-silver reserve battery comprises an activation circuit formed by connecting an activation power supply, a gas generator and an activation switch in series; the circuit is characterized in that a time-delay relay and an initiating explosive device current-limiting resistor are connected in series in the activation circuit; the resistance value of the initiating explosive device current-limiting resistor is 9.5 ohm + / -5%, and the activation power supply is a 28V + / -3.5 V direct-current power supply. By the adoption of the technical scheme, on the basis that the zinc-silver reserve battery pack can be reliably activated, the zinc-silver reserve battery pack has the advantages of being reasonable in structure, convenient to manufacture and install and low in cost.

Description

technical field [0001] The invention belongs to the technical field of zinc-silver reserve batteries, and in particular relates to a control circuit and a control method for activating circuit resistance of zinc-silver reserve batteries. Background technique [0002] Since the zinc-silver reserve battery has unique advantages such as stable discharge voltage, high voltage precision, good reliability and safety, it is widely used in various fields, especially suitable for equipment and instruments with high voltage precision. [0003] Zinc-silver reserve battery is mainly composed of combined plate group, liquid reservoir, pipeline, gas generator, shell and so on. The combined plate group is formed by connecting the plate groups in series. For long-term storage, the battery pack is stored separately from the electrolyte and the plate group before use. The electrolyte is stored in the liquid reservoir, and the liquid reservoir is connected to the combined The pole plate group...
