Abstract
The utility model discloses a hydraulic mechanism of a circuit breaker for on-line filtering. The hydraulic mechanism comprises a hydraulic fluid filter, a hydraulic fluid pump and a hydraulic fluid tank. The hydraulic mechanism adopts the main technique that the hydraulic fluid filter is externally arranged, and is positioned between the hydraulic fluid tank and the hydraulic fluid pump. The hydraulic mechanism has the advantages that the on-line overhauling is realized, the filtering effect is good, and the like.
Description
Technical field
The utility model relates to a kind of on-line filtration Hydraulic Mechanism of Circuit-breaker.
Background technique
Hydraulic mechanism is that the primary cut-out operating mechanism adopts more a kind of form, and hydraulic mechanism is a kind of device that relies on the hydraulic oil transmission of pressure, by the piston driving piston rod, and then drives moving contact of breaker, realizes that circuit breaker divides, closes a floodgate.The hydraulic oil rated oil pressure reaches 28Mpa.If hydraulic oil can not keep clean, even the impurity of molecule invades in high pressure oil, can cause that also valve channel in mechanism (pipeline) stops up or bite, makes the hydraulic pressure installation cisco unity malfunction.Therefore, the clean degree of hydraulic oil there is very high requirement.
At present, the hydraulic mechanism that electric power system is used, when hydraulic oil filter is carried out cleaning maintenance, need to disintegrate to equipment, need to have a power failure in doing the process of these work, this does not meet the present repair based on condition of component of carrying out of State Grid Corporation of China and the aim of hotline maintenance, and has increased workload, increases power off time.
According to statistics, the fault of hydraulic pressure installation (comprising the Hydraulic Mechanism of Circuit-breaker in electric power system), 70% is relevant with hydraulic oil, and this 90% is approximately because the impurity that contains in hydraulic oil causes in 70%.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of on-line filtration Hydraulic Mechanism of Circuit-breaker, the characteristics such as it has can on-bne repair, good filtration effect.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: it comprises hydraulic oil filter, hydraulic-pressure pump and hydraulic oil container, and key technology is that hydraulic oil filter is that external mode is installed, between hydraulic oil container and hydraulic-pressure pump.
The utility model further improves and is: hydraulic oil filter two ends are provided with stop valve and lower stop valve; Be provided with the auxiliary hydraulic pressure fuel tank with the hydraulic oil container horizontal position, be communicated with between the bottom of auxiliary hydraulic pressure fuel tank and lower stop valve and hydraulic-pressure pump; Hydraulic oil filter is y-type filter.
The beneficial effect that adopts technique scheme to produce is: hydraulic oil filter is that external mode is installed, between hydraulic oil container and hydraulic-pressure pump; Hydraulic oil filter is y-type filter, this kind structure can realize online (charged) filtration of hydraulic oil, need not hydraulic mechanism is disintegrated, can regularly the filter for molten filter core be taken out, carry out cleaning, to complete the maintenance to equipment, the repair cycle of extension device, improve the equipment reliability of operation; The hydraulic oil filter two ends are provided with stop valve and lower stop valve, be convenient to filter is cleaned, be provided with the auxiliary hydraulic pressure fuel tank with the hydraulic oil container horizontal position, be communicated with between the bottom of auxiliary hydraulic pressure fuel tank and lower stop valve and hydraulic-pressure pump, prevent when plugged filter, caused oil mass to reduce, in the inner vacuum that forms of oil pump oil circuit.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the accompanying drawings: 1, hydraulic oil filter; 2, hydraulic-pressure pump; 3, hydraulic oil container; 4, upper stop valve; 5, lower stop valve; 6, auxiliary hydraulic pressure fuel tank; 7, return tube.
Embodiment
By embodiment shown in Figure 1 as can be known: it comprises hydraulic oil filter 1, hydraulic-pressure pump 2 and hydraulic oil container 3, and key technology is that hydraulic oil filter 1 installs for external mode, between hydraulic oil container 3 and hydraulic-pressure pump 2.Hydraulic oil filter 1 adopts external mounting type can realize online (charged) filtration of hydraulic oil, the repair cycle of extension device, improves the equipment reliability of operation.
Hydraulic oil filter 1 two ends are provided with stop valve 4 and lower stop valve 5.Stop valve is elected ball valve as, is convenient to switch, when hydraulic oil filter 1 is overhauled, two stop valves in up and down is closed, and is convenient to it is overhauled.
Be provided with auxiliary hydraulic pressure fuel tank 6 with hydraulic oil container 3 horizontal positions, its oil reserve can provide hydraulic mechanism once to suppress oil mass used, is communicated with between the bottom of auxiliary hydraulic pressure fuel tank 6 and lower stop valve 5 and hydraulic-pressure pump 2.During the equipment on-line operation, fuel tank and service tank are intercommunications, and according to law of connected vessels, the low pressure oil in fuel tank enters service tank due to action of gravitation by filter, realizes the hydraulic oil on-line filtration.Auxiliary hydraulic pressure fuel tank 6 can also prevent from reducing because plugged filter causes oil mass, occurs in the inner phenomenon that forms vacuum of oil pump oil circuit.
Hydraulic oil filter 1 is y-type filter.During maintenance, do not need the oil in fuel tank is all emitted, can regularly the filter for molten filter core be taken out, carry out cleaning.
Working principle:
During the equipment on-line operation, hydraulic oil circulates in equipment, between carry out circulating filtration through hydraulic oil filter, hydraulic oil filter adopts external mounting type, can realize online (charged) filtration of hydraulic oil, during maintenance, not need the oil in fuel tank is all emitted, can regularly the filter for molten filter core be taken out, carry out cleaning.Before taking out filter core, first two stop valves in hydraulic oil filter up and down are closed, owing to being provided with the auxiliary hydraulic pressure fuel tank, according to law of connected vessels, low pressure oil in fuel tank enters service tank due to action of gravitation by filter, realizes the hydraulic oil on-line filtration, can also prevent from simultaneously reducing because plugged filter causes oil mass, occur in the inner phenomenon that forms vacuum of oil pump oil circuit.
