Abstract
The utility model provides a novel pointer-type oil level gauge for a transformer in order to solve the problem that an existing pointer-type oil level gauge is much wasteful, has the hidden danger of leakage and is high in maintenance cost and unsuitable for replacement. The novel pointer-type oil level gauge comprises an indicating cavity, a sealing cavity and a floating ball. The novel pointer-type oil level gauge is characterized in that the indicating cavity is connected with the sealing cavity through a bolt and then connected with the floating ball through a driving mechanism behind the sealing cavity, and the indicating cavity and the sealing cavity are connected with each other through a waterproof plug to transmit data. The novel pointer-type oil level gauge can accurately measure oil level and is low in cost, easy to replace, fine in operation condition and low in failure rate, and leakage is not easily caused.
Description
Technical field
The utility model relates to field transformer, especially a kind of novel transformer pointer type fuel level indicator.
Background technology
Pointer type fuel level indicator is important component on transformer oil storage.Because it has good looking appearance, can accurately indicate the characteristics such as oil level and output height warning signal to be subject to user's favor always.But along with the progress in epoch, the particularly development of intelligent grid and intelligent transformer in recent years, traditional pointer type fuel level indicator also exposes some shortcomings gradually.Such as, traditional pointer type fuel level indicator can not be exported the analog or digital signal of continuous representation oil level, in case maintenance just must be drained the oil to oil conservater etc.Figure 1 shows that traditional pointer type fuel level indicator structure.Its principle of work is by magnetic coupling force, the motion of the ball float in oil conservater is delivered to the inside of oil level indicator.Owing to having adopted magnetic coupling technology, inside and outside oil level indicator, isolation fully, guaranteed splendid sealing property, and this is also the advantage place of pointer oil level indicator.But the housing of its one casting has brought deficiency also: 1. waste of material is many.2. cast in back casing and may have the defects such as pore, sand holes, may cause occurring leakage problem.So 3. because be that monoblock cast can not split, in case oil level indicator breaks down, the user can't solve alone, after cost is high.4. during maintain and replace, must drain the oil to oil conservater, not only take time and effort and also easily cause the pollution to transformer oil.
Summary of the invention
In order to solve the problem that existing pointer type fuel level indicator waste is many, hidden danger is leaked in existence, maintenance cost is high and should not change, the utility model provides a kind of novel transformer pointer type fuel level indicator, not only can locate accurately oil level, and with low cost, easily change and be not easy produce to leak.
Described a kind of novel transformer pointer type fuel level indicator, by indication chamber, annular seal space and ball float, formed, it is characterized in that: the indication chamber is bolted annular seal space, by the gear train after annular seal space, connect ball float again, between indication chamber and annular seal space, by waterproof plug, is connected and transmits data simultaneously.
Described a kind of novel transformer pointer type fuel level indicator, be comprised of indication chamber, annular seal space and ball float, it is characterized in that: the indication chamber is comprised of dial plate, pointer, magnet steel seat, controller, and wherein, the magnet steel seat top sets gradually controller and dial plate; Pointer is fixed on the center position of dial plate by axle; The axle of fixed dial passes dial plate, controller and magnet steel seat successively simultaneously.
Described a kind of novel transformer pointer type fuel level indicator, be comprised of indication chamber, annular seal space and ball float, it is characterized in that: water proof wire from the controller in indication chamber, and the connection terminal of annular seal space in draw respectively, and be connected by waterproof plug.
The beneficial effects of the utility model are: not only can measure accurately oil level, and with low cost, easily change and be not easy produce to leak, operation conditions is good simultaneously, failure rate is extremely low.
The accompanying drawing explanation
Fig. 1 is traditional pointer type fuel level indicator structural drawing; Fig. 2 is novel transformer pointer type fuel level indicator.
Wherein, 1. dial plate; 2. pointer; 3. axle; 4. magnet steel seat; 5. controller; 6. indication chamber; 7. annular seal space; 8. connection terminal; 9. gear train; 10. ball float; 11. waterproof plug.
Embodiment
As shown in Figure 2, a kind of novel transformer pointer type fuel level indicator, by indication chamber, annular seal space and ball float, formed, its structure is: indication chamber 6 is bolted annular seal space 7, by the gear train 9 after annular seal space 7, connect ball floats 10 again, between indication chamber 6 and annular seal space 7, by waterproof plug 11, be connected and transmit data simultaneously; Wherein, indication chamber 6 is comprised of dial plate 1, pointer 2, magnet steel seat 4, controller 5, and wherein, magnet steel seat 4 tops set gradually controller 5 and dial plate 1; Pointer 2 is fixed on the center position of dial plate 1 by axle 3; The axle 3 of fixed dial passes dial plate 1, controller 5 and magnet steel seat 4 successively simultaneously; Water proof wire from the controller 5 in indication chamber 6, and the connection terminal 8 of annular seal space 7 in draw respectively, and be connected together by waterproof plug 11.
