Mining Flameproof and Intrinsically Safe Vacuum Electromagnetic Starter

Product Features

(1) Intelligent Setting

The intelligent electromagnetic starter is equipped with a low‑voltage intelligent protection device, featuring precise earth leakage protection to effectively prevent cascade tripping caused by earth leakage faults. In addition, with the integration of a smart setting system, the starter enables intelligent parameter setting — including one‑key setting, automatic rationality verification, and adaptive adjustment to load changes. This thoroughly solves the problem of parameter setting in coal mines, fully replacing the complex and tedious manual setting work of specialized personnel, ensuring settings are accurate and reasonable, and eliminating safety hazards caused by unscheduled or large‑scale power outages due to improper settings.

(2) Remote Earth Leakage Test

The intelligent electromagnetic starter integrates a remote earth leakage test device, which allows remote control of the starter and grounding of the test resistor within the remote test device. It automatically performs the earth leakage test for branch feeders, restores power automatically, and generates test reports — eliminating the issues of "skipping tests" or "false testing" in remote leakage tests. Test personnel do not need to go underground, reducing labor intensity and improving test efficiency. This system requires no additional external test equipment.

(3) Remote Intelligent Monitoring

Equipped with remote intelligent monitoring capabilities, including "four‑remote" functions (telemetry, remote signaling, remote control, and remote adjustment), it fills the gap in the intelligent construction of low‑voltage distribution equipment at mining power distribution points and working faces.

(4) Precision Metering

Real‑time monitoring of voltage, current, and power factor for each phase of three‑phase motors, with calculation of instantaneous and cumulative electrical energy consumption for optimized energy efficiency.

(5) Automatic Water Supply

Features remote monitoring and automatic water level control functions. Through remote monitoring of the water intake system, it enables unattended operation of the main mine drainage system, and can also achieve unattended operation of submersible pumps underground.
