Abstract
The invention discloses a floater used in a transformer oil level indicator. The floater comprises a solid floater body, a connecting rod connected with an oil level indicator pointer is arranged at one end of the floater body, and a sensor connected with a circuit board is arranged in the floater body. Due to adoption of the solid floater body, shriveling of the floater when a transformer is in a vacuum test can be avoided; the sensor is arranged in the floater, so that when the pointer in the oil level indicator ascends to the highest point or descends to the lowest point, the sensor sends out a signal to prompt operating personnel to control the oil level in a transformer oil tank, and the floater is safe, reliable and convenient to use.
Description
Technical field
The present invention relates to field transformer, particularly relate to a kind of for the float in the oil level gauge for transformer.
Background technology
The general one section steel pitman of hollow stainless steel ball welding that adopts of the float of existing oil level meter for transformer forms.Adopt inferior arc welding between hollow stainless steel ball and the steel pitman, because hollow stainless steel ball wall thickness between 0.3 to 0.5 millimeter, so form easily the defectives such as rosin joint, not prison welding, causes the oil level indicator indication malfunctioning; Do to vacuumize when test at transformer, sometimes can occur hollow stainless steel ball is taken out flat phenomenon; Float is immersed in the transformer oil at ordinary times, the phenomenon that hollow stainless steel ball infilters oil sometimes can occur, thereby cause hollow stainless steel floating ball loss of buoyance; When oily too much or very few in the fuel tank, can not in time remind the staff.These all can affect the oil level indicator normal operation.
Summary of the invention
The technical matters that the present invention mainly solves provides a kind of simple in structure, easy to process, safe and reliable float that is used in the oil level gauge for transformer.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of for the float in the oil level gauge for transformer, comprise solid float body, described float body one end is provided with the connecting rod that is connected with the oil level indicator pointer, is provided with the sensor that is connected with wiring board in the described float body.
In a preferred embodiment of the present invention, described float body is polyurethane material.
In a preferred embodiment of the present invention, described float body is square.
In a preferred embodiment of the present invention, described float body outside surface is coated with color.
In a preferred embodiment of the present invention, described float body and connecting rod are one-body molded.
The invention has the beneficial effects as follows: the present invention is used for the float in the oil level gauge for transformer owing to adopt solid float, float can not occur and do phenomenon shrivelled in the vacuum test at transformer, owing to be provided with sensor in the float, when pointer in the oil level indicator rises to the highest or reduces as far as possible, sensor sends signal, remind operating personnel that oil level in the oil tank of transformer is controlled, safe and reliable, easy to use.
Description of drawings
Fig. 1 is the perspective view that the present invention is used for float one preferred embodiment in the oil level gauge for transformer;
The mark of each parts is as follows in the accompanying drawing: 1, float body, 2, connecting rod, 3, sensor.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the invention comprises:
A kind of for the float in the oil level gauge for transformer, comprise solid float body 1, described float body 1 one ends are provided with the connecting rod 2 that is connected with the oil level indicator pointer, are provided with the sensor 3 that is connected with wiring board in the described float body 1.
Described float body 1 is polyurethane material, is square, and by the not oil suction of float of polyurethane material foaming, oil-tight, effect is better.
Described float body 1 outside surface is coated with color, is easy to observe the particular location of float.
Described float body 1 is one-body molded, easy to process, not easily separated with connecting rod 2.
Compared with prior art, the present invention is used for the float in the oil level gauge for transformer owing to adopt solid float, float can not occur and do phenomenon shrivelled in the vacuum test at transformer, owing to be provided with sensor 3 in the float, when pointer in the oil level indicator rose to the highest or reduces as far as possible, sensor 3 sent signal, reminded operating personnel that oil level in the oil tank of transformer is controlled, safe and reliable, easy to use.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes instructions of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
