Problems solved by technology

At present, the hydraulic oil of the hydraulic mechanism is injected into the low-pressure oil tank of the hydraulic mechanism from the oil filling port by using an oil barrel and an oil scoop, which has low working efficiency and may add impurities into the oil tank, which will affect the normal operation of the circuit breaker, and when refueling due to The space inside the mechanism box where the low-pressure oil tank is placed is small, the hydraulic oil is easy to spill, it is troublesome to clean up, and it will cause environmental pollution and other problems

Embodiment 1

[0022] Embodiment one: if figure 1 As shown, the present invention provides a low-pressure oil tank for a hydraulic mechanism of a circuit breaker, which includes an oil tank body 1, an oil inlet 2 is arranged at the upper end of the oil tank body 1, and an oil discharge port 3 is arranged at the lower end of the oil tank body 1. The oil inlet 2 is connected with an oil injection pipe joint 4, and an oil-water separator 6, a filter 7, an oil pump 8 and a first valve 9 are sequentially connected between the oil injection pipe joint 4 and the oil discharge port 3 through an oil delivery pipeline 5. The oil delivery pipeline 5 between the first valve 9 and the oil pump 8 is also provided with an oil suction pipeline 10 on which a second valve 11 is provided.

[0023] The existing low-pressure oil tank only has oil filling port and oil discharge port 3. When the hydraulic oil in the low-pressure oil tank is not enough, it needs to be replenished manually. The hydraulic oil in the...

Embodiment 2

[0029] Embodiment two: if figure 2 As shown, on the basis of the first embodiment, the oil injection pipe joint 4 is provided with a third valve 14. When the low-pressure fuel tank is in normal use, the first valve 9 and the third valve 14 are closed, and the low-pressure fuel tank is only connected to the hydraulic mechanism. Components are connected, not connected with the oil supply pipeline 5, so that the pressure in the low-pressure fuel tank will not enter the oil supply pipeline 5, causing impact and impact on the oil-water separator 6, filter 7, oil pump 8, etc.

[0030] The oil suction pipeline 10 is a rubber hose, the shape of the rubber hose is changeable, it is convenient to be inserted into an external oil container, and it is flexible and convenient to use.

[0031] The present invention also provides a method for quickly replenishing oil based on the low-pressure fuel tank for the hydraulic mechanism of the circuit breaker. When the low-pressure fuel tank is in...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a low-pressure oil tank for a hydraulic mechanism of a circuit breaker and a method for rapidly replenishing oil thereof. Background technique [0002] The hydraulic mechanism has the advantages of large operating power and stable operation. It is generally used in high-voltage circuit breakers of 220kV and above. However, due to the harsh working environment and long-term use of the hydraulic mechanism, oil leakage will occur. At this time, maintenance personnel need to replenish hydraulic oil in time as needed. At present, the hydraulic oil of the hydraulic mechanism is injected into the low-pressure oil tank of the hydraulic mechanism from the oil injection port by using an oil barrel and an oil scoop, which has low working efficiency and may add impurities to the oil tank, which will affect the normal operation of the circuit breaker, and when refueling due to The s...
