The switch status indicator is a multifunctional and intelligent analog dynamic indicator device used on switchgear. It has indication functions such as primary circuit simulation diagram, switch status, circuit breaker position, grounding switch position, spring energy storage status, high-voltage live indication, heater fault indication, etc. It also has high-voltage live locking, automatic heating control, temperature control, and other control functions.
It integrates multiple functions such as primary circuit simulation diagram, circuit breaker position, switch status, grounding switch position, spring energy storage status, high-voltage live indication, high-voltage point locking, and temperature and humidity control. The indication function can be divided or combined, and users only need to provide a scheme diagram when selecting. In addition, the product can also achieve integrated layout and supporting equipment for circuit power parameters, temperature, humidity and other control functions according to user requirements, which will simplify the panel layout of previous switchgear. It will replace various control and indication devices such as existing primary circuit analog indicator boards, electromagnetic switch status indicators, and grounding indicators. At the same time, it will be equipped with communication functions and can upload all switch status and temperature and humidity conditions to the monitoring center The switch status simulation indicator has high-voltage live indication functions such as primary circuit simulation diagram, switch status, circuit breaker position, grounding knife position, spring energy storage status, high-voltage live locking, automatic heating and dehumidification control, temperature control, and heater fault indication. The status indicator has a small volume, insulated plastic shell, and flexible and convenient installation position of the switch status indicator, which is deeply loved by customers. The present invention discloses a switch cabinet status comprehensive indicator and a status indication method. The switch status comprehensive indicator comprises a shell and a circuit board arranged inside the shell. The circuit board is integrated with a main controller, a temperature and humidity acquisition circuit, a three-phase live indication circuit, an analog signal acquisition circuit, an analog display circuit, and a fault diagnosis circuit. The temperature and humidity acquisition circuit, a three-phase live indication circuit, an analog signal acquisition circuit, an analog display circuit, and a fault diagnosis circuit are respectively connected to the main controller. The present invention can display the switch status, circuit breaker position, grounding switch position, spring energy storage status, and heater status, and indicate the high-voltage live and high-voltage live locking status, and can automatically or manually control heating and dehumidification
