Description

Low voltage circuit breaker status remote monitoring device

This invention creates a low-voltage circuit breaker status remote monitoring device, which can improve the conventional isolation equipment of the low-voltage distribution system AC voltage within 600 volts, which is generally based on fusible circuit breakers or molded case circuit breakers. , as a fault current protection on the power circuit line, or as an overload protection for the load equipment, in an electrically driven manner, it is impossible to remotely monitor and control the status of the circuit breaker on the power distribution equipment whose status point is on site. For electric operation, remote monitoring and control of the low-voltage circuit breaker must be used in special places due to distance and environmental factors. There are difficulties. The above problems are problems that cannot be solved in the traditional knowledge and skills.

The current method of electrically driving a low-voltage circuit breaker on the market is to place an electric motor drive device above the low-voltage circuit breaker. The electric drive device is generally supplied with AC or DC as the control power supply, and the power supply voltage is also divided into 12V. , 24V, 48V, 110V, 220V, etc., there are many types and complex, and because of the different power supply circuit systems, the number of poles of low-voltage switches is divided into 2-phase, 3-phase, 4-phase, etc., and is roughly divided into molded case circuit breaker circuit breaker, leakage circuit breaker, etc..., there are too many brands and too many specifications, which makes integration difficult. The above problems cannot be effectively overcome by the products currently on the market and cannot achieve the function of remote monitoring of the low-voltage circuit breaker.

Accessories of low-voltage circuit breakers currently on the market, such as auxiliary contacts, can be used to understand the current status of the low-voltage circuit breaker, such as in the closed ON position or the open/closed OFF position; such as split-trip trip coils, which can be energized by external instructions. Make the low-voltage switch trip and cut off power; if the voltage is insufficient to trip the coil, it can be controlled by the external command to determine whether it is conductive or not. It will not operate when there is power, and it will operate when there is no power or less than 80% of the rated voltage and limit the low-voltage circuit break. The tripping mechanism of the low-voltage circuit breaker is locked and cannot perform the closing or opening functions; if there is an accessory called an alarm auxiliary contact, its function is to trip when the overcurrent protection element inside the low-voltage circuit breaker is tripped due to overload or fault conditions. Or the shunt trip coil is activated or the under-voltage trip coil is activated. At this time, the alarm auxiliary contact is conductive, otherwise it will not activate.
