Abstract
The utility model belongs to a component of a transformer which is mainly used on a completely enclosed oil filling and power distributing transformer. The utility model includes a pipe body, a sealing element, etc., and is characterized in: the upper part of the pipe body is provided with one or more observation windows, a bobber is arranged in the lower part of the pipe body and a marking element floats on the bobber; the pipe body is provided with a flange cover or a pressure releasing valve which is used for the placement of an air releasing piston or an air sampling valve; a bobber limit element is included in the utility model and the flange cover can be provided with a magnetic switch etc; the bobber is also provided with a switch. The utility model can display the lowest oil level, protects the oil from being illuminated by the sunshine, monitors the lowest oil level or excess air, collects the air or release the pressure, etc.
Description
The utility model belongs to a kind of parts of transformer, be mounted on the transformer case in order to show oil level in the fuel tank or to store the device of the gas that produces in the fuel tank, and venting, minimum oil level or functions such as excess air monitoring, pressure release are arranged, mainly be applicable to hermetically sealed oil-filled substation transformer.
At present, the purpose of the used tubular type oil level gage of hermetically sealed oil-filled substation transformer is the oil level that shows in the fuel tank.Its structure is: one with metal tube that fuel tank internal communicates on have inspection hole, and sealing is equipped with formations such as the glass tube of observing oil level or glass plate on inspection hole.Its weak point is: 1, because this structure inspection hole all is higher than the fuel tank upper surface, can't open inspection hole in the lower end near oil meter, when oil level during near fuel tank cap, oil meter does not just have pasta and shows, be mistaken as the fuel tank oil starvation, therefore can not show oil level near the oil meter bottom; 2, because pasta directly by the inspection hole demonstration, therefore, makes oil directly be subjected to sunlight and ultraviolet irradiation, easily aged deterioration of oil; 3, because the volume of oil level gage is less, therefore can not gather the gas that produces in the fuel tank, particularly hinder the inflammable gas that produces for some reason; 4, since the oil level of this structure by range estimation, therefore to because of the fuel tank inner oil shortage or produce excessive gas and can not in time monitor; 5, because of its body above fuel tank cap, therefore the oil level at the fuel tank internal upper part can not show.
The purpose of this utility model is to overcome the weak point in the above-mentioned prior art, and the minimum oil level that can accurately show the fuel tank internal upper part is provided, prevents solar radiation oil, minimum oil level or excess air can be in time monitored, a kind of multi-functional tubular type oil level indicator that gas or pressure discharge can be gathered.
The purpose of this utility model can reach by following measure, comprise body, seal etc., its special character is: have one or several inspection hole on the top of body, be equipped with and inboard wall of tube body sealed glass pipe at the inspection hole place, bottom in body is equipped with float, being equipped with top on float has the mark spare that shows the oil level mark, is equipped with blind flange or the pressure relief valve of being with air relief cock or getting gas sample valve in the sealing of the upper end of body; On the body lower inner wall, be provided with the locating part of float domain of walker; The mid-switch that is magnetic in hole that also can a side is provided with in the flange lid, and in the blind flange center pit, be equipped with the actuating lever that top has the magnet that matches with magnetic switch, the lower end of actuating lever is fixed with the catch that drops on oil level mark spare upper end; Center at float also can be provided with oil through; The lower end of body can extend to joint flange below, and around its prolongation, be provided with oil through.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of another embodiment of the utility model.
See figures.1.and.2.Embodiment of the present utility model has one or several inspection hole 1S on the top of body 1, be equipped with at inspection hole 1S place with body 1 inwall through O-ring seal 12 sealed glass pipes 4.Bottom in body 1 is equipped with float 2.On float 2, be equipped with top the mark spare 3 that shows the oil level mark is arranged.O-ring seal 11 sealings are equipped with blind flange 6 or the pressure relief valve 17 of being with air relief cock or getting gas sample valve 10 on the warp of the upper end of body 1.For to minimum oil level or excessive gas, particularly the inflammable gas of fault generation is in time monitored, the mid-switch 7 that is magnetic in hole that also can a side is provided with in blind flange 6 bodies, and in blind flange 6 center pits, being equipped with the actuating lever 9 that top has the magnet 8 that matches with magnetic switch 7, the lower end of actuating lever 9 is fixed with the catch 5 that drops on oil level mark spare 3 upper ends.Install also and can turn to fuel tank cap for body 1, steering ring 14, joint flange 15, lower seal 16 etc. also are housed in the bottom of body 1.On body 1 lower inner wall, also be provided with the locating part 13 of the domain of walker of float 9.Center at float 2 also can be provided with oil through 2K.The lower end of body 1 can extend to joint flange 15 below, and around its prolongation, be provided with the hole 1K of logical oil or gas.
The utility model compared with the prior art good effect is as follows:
1, because the utility model is located at the bottom of body with float, and inspection hole is opened upper at body Section shows oil level by the oil level mark spare in buoy upper, therefore, not only can show exactly Minimum oil level, and can prevent solar radiation oil, and in the body upper chambers, can store enough Get gas sample quantity;
2, because the utility model is provided with magnetic switch and the starting bar of the carry magnet that matches with it etc., Therefore can in time monitor minimum oil level or excess air by the signal of telecommunication that magnetic switch sends;
3, owing on the flange of body upper end, have air relief cock or get gas sample valve or pressure relief valve, therefore can exit or gather gas sample or pressure release etc.;
4, because the lower end of body can extend to the top in the fuel tank, and around its prolongation, be provided with oil through, therefore can show the oil level of fuel tank internal upper part.
Claims (5)
