Overview: the GD-MF arrester seal-check heating water bath comprises a water tank, a heating device, a digital temperature controller and a temperature sensor. The tank side wall has insulation, a water inlet and a water outlet; the heater raises the water temperature to the required level; and the temperature sensor connects to the digital controller.
Safety and mobility: the tank side wall has a heat-insulation layer to prevent scalding during heating, and the whole assembly is integrated into one box with castors at the four corners for easy movement.
Temperature control: the digital temperature controller supports RTD signals at 0.1% resolution and thermocouple signals at 1°C resolution, with 0.3% measurement accuracy and upper/lower limit alarm. The heating device runs on 380V at 30kW.
Test requirements: the water must be clean and the water temperature 45°C±5K above the environment temperature. The arrester is immersed horizontally with the water surface 10-20cm above its highest point. Immersion time is at least 10 minutes below 42kV and at least 30 minutes at 42kV and above.
