The switch status indicator is a new type of multifunctional, intelligent dynamic analog indicator developed and designed according to the current development of medium voltage system switch cabinet technology. It integrates primary circuit simulation, switch status, circuit breaker position, grounding knife position, spring energy storage status and other multifunctional functions. These indication functions can be separated or combined, and users can choose according to their needs. Just specify different order models and provide a primary scheme diagram.

This product is integrated into the switch cabinet, which will simplify the switch cabinet panel structure design, beautify the switch cabinet panel layout, and improve the switch status indication function and safety performance.

Features

◆ Operating environment: -10℃～50℃, <95%RH;

◆ Storage environment: -40℃~80℃, <95%RH;

◆ Dielectric strength: >AG2000V between shell and terminal;

◆ Insulation performance: >100M between the shell and the terminal;

◆ Analog display part: working power supply: DC110V DG220V AG220V (selected by the user when ordering), working current: <30mA;

◆ Disconnector switch indication: In normal state, the green analog bar of the “V”-shaped digital tube lights up; when the disconnector switch is closed, the red analog bar of the “V”-shaped digital tube lights up;

◆ Circuit breaker status indication: Circuit breaker opening and closing, passive contact input; when the isolating switch is closed, the red analog bar of the "V"-shaped digital tube lights up; when the circuit breaker is closed, the closing contact is closed, and the red analog bar of the "V"-shaped digital tube lights up; when the circuit breaker is open, the opening contact is closed, and the green analog bar of the "V"-shaped digital tube lights up;

◆ Working position indication: Passive contact input; when the working position contact is closed, the red vertical analog bar of the "X"-shaped digital tube lights up, indicating that the circuit breaker is in the working position; when the test position contact is closed, the green horizontal analog bar of the "X"-shaped digital tube lights up, indicating that the circuit breaker is in the test position. When the power is off, both the red and green light bars are off, indicating the power-off state;

◆ Indication of grounding switch position: When the passive contact input is closed, the red analog bar of the "V"-shaped digital tube lights up, indicating that the grounding switch is closed; when the passive contact input is disconnected, the green analog bar of the "V"-shaped digital tube lights up, indicating that the grounding switch is disconnected;

◆ Spring energy storage indication: When the passive contact input is closed, the red spring symbol lights up, indicating that energy has been stored; when the passive contact input is disconnected, the green spring symbol lights up, indicating that no energy has been stored.
