Problems solved by technology

This method is relatively complicated, and the switching is also prone to failure. However, the operation cost of deep-sea equipment is relatively high. If the actuator cannot provide reliable power supply, it needs to return to the water surface, which greatly wastes manpower, material resources and financial resources.

Abstract

The invention discloses a deep-sea high-power capacitive load DC contact protector, which relates to the field of DC contact protectors and includes: a contactor switch, a time-delay bypass circuit, a washer and a waist-shaped copper sleeve; a wiring copper post of the contactor switch Connect and fix with the delay bypass circuit through the washer and the waist-shaped copper sleeve; the delay bypass circuit is used to slowly charge the capacitive load to the power supply voltage before the contacts of the contactor switch are connected; the washer is used to support The delay bypass circuit; the waist-shaped copper sleeve is used to conduct the large current of the contactor contact to the external load terminal; the coil power line of the contactor switch is connected to the terminal of the protection circuit. The deep-sea high-power capacitive load will not generate a large current impact when it is powered on, which not only protects the safety of its own equipment, but also avoids the impact on the power system. When the power is turned off, the contactor coil will not generate high induced voltage, which improves the safety of power supply. performance, which can increase the service life of the contactor.

Description

technical field [0001] The invention relates to the field of direct-current contact protectors, in particular to a deep-sea high-power capacitive load direct-current contact protector. Background technique [0002] Deep-sea equipment such as deep-sea submersibles need to be equipped with various types of actuators. These actuators are mainly divided into hydraulic actuators. The power of hydraulic actuators comes from a high-power hydraulic source. The driving mechanism of the hydraulic source is a DC motor. Therefore, DC Motors are widely used actuators in deep sea equipment. DC motor is an inductive load, which is sensitive to current changes. In order to ensure the stability of DC motor operation, its driver often needs to install a large-capacity capacitor as an energy storage device, so the driver is an important part of the power supply. A high-power capacitive load, the power can reach tens of kilowatts, and the voltage can reach thousands of volts. [0003] In the ...
