Abstract
An oil level observation window of a hydraulic control mechanism used for a circuit breaker comprises an oil window which is hermetically connected on the milling concave plane at the upper part on one side of an oil tank, and is characterized in that a strip-shaped oil circuit is arranged on the inner side of the oil window; an upper oil flow hole and a lower oil flow hole which are communicated with a hydraulic oil in the oil tank are formed on the milling concave plane at the upper part on the side of the oil tank; and the two oil flow holes are opposite to the two ends of the strip-shaped oil circuit of the oil window so as to form a communicating vessel. The hydraulic oil level in the oil window and the actual hydraulic oil level in the oil tank rise at the same time and keep the same height, so as to meet the requirement that a user observes the filling quantity of hydraulic oil. In the utility model, since the oil circuit is longer, the observation range is widened, and the requirements of practical observation of the user are met.
Description
Technical field
The utility model relates to a kind of circuit breaker hydraulic actuating mechanism oil level finder.
Background technology
Hydraulic pressure spring operating mechanism is a kind of powder operation device of electrical network mesohigh circuit breaker, and hydraulic oil is the medium of this powder operation device transferring power.Whether hydraulic oil dress charge the suitable mechanical property that directly affects hydraulic spring mechanism, observes oil level by observation window and passes judgment on and whether oil-filled amount is suitable, and visible oil level glass is a kind of important components on the hydraulic actuating mechanism.The hydraulic mechanism operating state is horizontal mounting means, and oily window is above the side of fuel tank.Original a kind of oil level glass is the circular oily window (Fig. 1) of single hole, when the oil-filled liquid level of fuel tank exceeds oily window fuel feed hole upper edge, having blocked the outlet of oily window upper gas can't discharge, oil window inner fluid face can not rise with fuel tank inner fluid face when filling hydraulic oil again in the fuel tank, and this moment, oily window liquid level can not reflect real oil-filled amount in the fuel tank; When liquid level drops to oily window fuel feed hole lower edge, can't observe liquid level, make troubles to user's monitoring.
Summary of the invention
The purpose of this utility model provides interior hydraulic pressure pasta of a kind of oily window and fuel tank interior actual hydraulic pressure oil level lifting simultaneously and keeps contour oil level glass.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of circuit breaker hydraulic actuating mechanism oil level glass, comprise that being sealedly connected on tank side top mills oily window on the concave plane, it is characterized in that, described oily window inboard is provided with the strip oil circuit, described tank side top mill have on the concave plane upper and lower two with fuel tank in the oil-through hole of hydraulic oil UNICOM, the relative linker that forms of these two oil-through holes with the two ends of oily window strip oil circuit.
In the such scheme, the oil at corresponding described strip oil circuit two ends surface is outside window gone up mark graduation mark up and down.The last oil-through hole of described fuel tank is the axis horizontal hole.Described oily window strip oil circuit is concealed or unenclosed construction.
Innovative point of the present utility model is to bore two oil-through holes and the inboard long strip type oil circuit formation of oily window linker up and down at fuel tank, interior hydraulic pressure pasta of oil window and fuel tank interior actual hydraulic pressure oil level lifting simultaneously also keep contour, satisfy the user and observe the requirement of hydraulic oil dress charge, oil surface is outside window carved two lines, and the zone is suitable hydraulic oil dress charge liquid level district between line.For user's monitoring, debugging bring convenience.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the circular oily window schematic diagram of a kind of existing single hole on the oil cylinder.
Fig. 2 be the utility model oil level glass on oil cylinder scheme of installation.
Fig. 3 Fig. 4 is first example structure of the utility model oil level glass figure.Wherein Fig. 4 is the end view of Fig. 3.
Fig. 5 Fig. 6 is for being second example structure figure of the utility model oil level glass.Wherein Fig. 6 is the end view of Fig. 5.
Fig. 7 Fig. 8 is for being the 3rd example structure figure of the utility model oil level glass.Wherein Fig. 8 is the end view of Fig. 7.
Among Fig. 1 to Fig. 8: 1, fuel tank; 2, low oil level; 3, oily window; 4, but the highest raise-position of oily window liquid level is put; 5, the gas that can not discharge; 6, high oil level; 7, oil circuit; 8, oil-through hole; 9, oily window installing hole; 10, sealing ring; 11, graduation mark.
Embodiment
As shown in Figure 2: the utility model oil level glass material is a transparent organic glass, and it is fixed in and mills on the fuel tank on the recessed plane by screw, sealing ring 10 (Fig. 3).Oil circuit 7 two ends are communicated with two oil-through holes 8 up and down of fuel tank 1, form linker, the aperture external seal. the last oil-through hole of fuel tank is processed as axis horizontal, can effectively discharge gas in the oily window 3, guarantee of the lifting simultaneously lifting of the interior hydraulic pressure pasta of oily window, and keep same horizontal level along with liquid level in the fuel tank.Longer because of the oil circuit 7 of novel oily window, widened observation scope, satisfy user's actual observation needs, oil outside window on the surface mark graduation mark 11 (Fig. 4) be convenient to more accurately judge that oil level is whether in suitable scope.
Shown in Figure 4 as Fig. 3, a specific embodiment of the utility model oil window 7 is concealed for oil circuit 7 is made strip in oily window inboard, only reserves the oil circuit two ends by two independent sealing ring UNICOM oil-through holes 8.
The utility model is not limited to Fig. 3 embodiment shown in Figure 4.As Fig. 5 Fig. 6 and Fig. 7 execution mode of two kinds of oily windows in addition shown in Figure 8, oil circuit and sealing means have changed, and promptly oil circuit 7 becomes the strip open type, and one of sealing means is hermetically sealed (Fig. 8); One only is Long Circle sealing (Fig. 6), but oil-through hole 8 passed in and out microscler oil circuit 7 in the cuboid oil windows about hydraulic oil passed through in the fuel tank, and the basic point that the oil level variation is observed in realization does not in a big way become.
Claims (4)
1, a kind of circuit breaker hydraulic actuating mechanism oil level glass, comprise that being sealedly connected on tank side top mills oily window on the concave plane, it is characterized in that, described oily window inboard is provided with the strip oil circuit, described tank side top mill have on the concave plane upper and lower two with fuel tank in the oil-through hole of hydraulic oil UNICOM, the relative linker that forms of these two oil-through holes with the two ends of oily window strip oil circuit.
