Description
Technical field
The utility model is related to the volume-variation compensation arrangement of transformer and power equipment configuration use, specifically a kind of fuel-saving type inner oil type metal bellow oil conservator.
Background technology
The wavy metal oil storage used at oil-immersed type power coordinative composition of equipments at present has certain Iinvalid volume when closing, and makes it Iinvalid volume must be full of when initial oiling, adds product use cost.When ripple core body vacuumizes, upper-lower seal plate lifting surface area is large, and distortion is large, easily produces permanent deformation.
Utility model content
Having Iinvalid volume to solve existing wavy metal compensating body, easily producing the problem of permanent deformation when vacuumizing, the purpose of this utility model is to provide a kind of fuel-saving type inner oil type metal bellow oil conservator.This fuel-saving type inner oil type metal bellow oil conservator decreases invalid compensation volume, reasonable stress under vacuum conditions.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises cabinet and is placed in the wavy metal compensating body in this cabinet, the lower seal plate of described wavy metal compensating body is to wavy metal compensating body inner recess, the space forming the invalid compensation volume of reduction, the top of described wavy metal compensating body is provided with the gas exhaust piping of discharging internal gas, bottom is provided with the pipeline road be communicated with oil tank of transformer, forms hermetic oil piping system.
Wherein: the upper sealing panel of described wavy metal compensating body is provided with oil level indicating device, described cabinet is provided with the oil level glass observing this oil level indicating device; The mid portion of described lower seal plate is to wavy metal compensating body inner recess.
Advantage of the present utility model and good effect are:
1. the lower seal plate of wavy metal compensating body caves inward by the utility model, formed and reduce the space of invalid compensation volume, save unnecessary oil reserve, and uniform force under vacuum conditions, improve the useful life of ripple core body, ensure that the safe operation of transformer.
2. the utility model operates steadily, and oil level instruction is accurately directly perceived, effectively protects the oil of transformer, ensure that the useful life equal with transformer.
3. the utility model has completely cut off the contact with outside air, protects oil, reduces the cost of transformer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1 is cabinet, 2 is gas exhaust piping, and 3 is wavy metal compensating body, and 4 is oil level indicating device, and 5 is oil level glass, and 6 is pipeline road, and 7 is upper sealing panel, and 8 is lower seal plate, and 9 is space.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, fuel-saving type inner oil type metal bellow oil conservator of the present utility model comprises cabinet 1 and is placed in the wavy metal compensating body 3 in this cabinet 1, and the lower seal plate 8 of wavy metal compensating body 3 is to wavy metal compensating body 3 inner recess, the space 9 forming the invalid compensation volume of reduction; The present embodiment is that the mid portion of lower seal plate 8 is to wavy metal compensating body 3 inner recess, which reduce the internal capacity of wavy metal compensating body 3, and then reduce invalid compensation volume, carry out the change of compensator transformer oil volume with the change of volume, save unnecessary oil reserve.
The top of wavy metal compensating body 3 is provided with gas exhaust piping 2, for discharging the gas of wavy metal compensating body 3 inside; Bottom is provided with the pipeline road 6 be communicated with oil tank of transformer, is formed real hermetically sealed oil piping system with this.
The upper sealing panel 7 of wavy metal compensating body 3 is provided with oil level indicating device 4, and cabinet 1 is provided with oil level glass 5, can be observed the real time position of oil level by the oil level glass 5 on cabinet 1 intuitively and accurately; The oil level indicating device 4 of the present embodiment can be oil level indicating arm.When temperature of oil in transformer changes, wavy metal compensating body 3 is by expanding or shrinking to compensate the change of oil volume.
Upper and lower sealing plate 7,8 uniform force under vacuum conditions of wavy metal compensating body 3, improves the useful life of ripple core body, ensure that the safe operation of transformer.
The utility model operates steadily, and oil level instruction is accurately directly perceived, effectively protects the oil of transformer, ensure that the useful life equal with transformer.
Claims (3)
