- Abstract:
- High voltage isolation switch is widely used in power grid. Its performance directly determines the safety of electricity consumption. In order to evaluate the performance of gw46-126 high-voltage isolation switch at different ambient temperatures, the experimental research on the contact clamping force, contact relative position, mechanism operating torque, output Angle of mechanism, circuit resistance and other parameters of the isolation switch under the temperature within the temperature range of ±60℃ in climate laboratory are conducted to get the trend and relationship between the qualities and temperature. Through experimental data collection and analysis, the influence law of environmental temperature change on the characteristics of isolation switch is determined, which provides important data support for further optimizing the performance of GW46-126 high-voltage isolation switch and improving the applicability of environmental temperature
