More Information
Summary:The utility model discloses a manual hot-line oil making-up device of high-voltage oil circuit breaker which mainly solves the problems that the prior high-voltage oil circuit breaker must be power off when the high-voltage oil circuit breaker is supplied with oil, has overmuch operation projects, higher danger of overhead works, low working efficiency and so on. Both ends of an oil inlet pipe of the device are respectively communicated with an oil tank and an oil pump, an outlet of the oil pump is provided with a tee, one end of the tee is provided with a pressure relieving valve, another end is communicated with an oil outlet pipe through an outlet connector of the oil pump, the other end of the oil outlet pipe is connected with a dedicated oil nipple, and the dedicated oil nipple is connected with the high-voltage oil circuit breaker through an oil drain valve of the circuit breaker. The device realizes the on-line overhaul and is suitable for the oil making-up operation of various models of high-voltage oil circuit breakers.
