Low-pressure oil tank for circuit breaker hydraulic mechanism and rapid oil supplementing method thereof

The invention discloses a low-pressure oil tank for a circuit breaker hydraulic mechanism and a rapid oil supplementing method thereof. The low-pressure oil tank comprises an oil tank body, an oil inlet is formed in the upper end of the oil tank body, an oil draining opening is formed in the lower end of the oil tank body, the oil inlet is connected with an oil injection pipe joint, an oil and water separator, a filter, an oil pump and a first valve are sequentially connected between the oil injection pipe joint and the oil draining opening through an oil conveying pipeline, an oil pumping pipeline is arranged on the oil conveying pipeline between the first valve and the oil pump, and a second valve is arranged on the oil pumping pipeline. The low-pressure oil tank is simple in structure,through the oil pump, the low-pressure oil tank can be subjected to rapid oil supplementing, the oil supplementing efficiency is high, during oiling, sprinkling is avoided, and the oil tank is safe and free of pollution. 本发明公
