Abstract

The invention discloses a circuit protection monitor for a battery-powered servo control system. The circuit protection monitor comprises a protection monitor body, a connecting plate is mounted at the rear end of the protection monitor body, and a heat dissipation window is installed on each of the upper and lower sides of the protection monitor body. According to the device, a plurality of groups of IGBTs connected in parallel are used in an anti-surge soft starting module inside the device to replace a traditional relay or contactor, so that the product size is reduced, the noise is reduced, the energy consumption is reduced, and the service life is prolonged. According to the device, a comprehensive CAN BUS high-speed bus communication module is adopted, various baud rates and communication ID combinations can be configured, the device adapts to a personalized scheme of a customer, and the communication safety of a product and a customer bus is protected by adopting an isolated communication design. According to the device, through various customized protection voltage settings, a built-in brake module consumes impact energy, and a client energy consumption resistor can be externally connected, so that the use flexibility of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, in particular to a circuit protection monitor for a battery-powered servo control system. Background technique [0002] In a battery-powered servo system, because there is a large-capacity capacitor in the back-end load, the low-voltage DC power supply will instantly charge both ends of the capacitor when the system is powered on. Equivalent to a short circuit state. The instantaneous short-circuit state will cause the output current of the DC power supply to soar to hundreds of amperes to thousands of amperes, and the instantaneous high-current impact will cause the power supply protection to have no output, and will also cause the subsequent load to stop working. [0003] In a battery-powered servo system, if there are electric actuators in the system, when these devices are in the process of emergency deceleration or braking, the mechanical energy will be converted into electrical ...
