Abstract

In order to solve the problems that a conventional pointer type oil-level gauge is large in waste, high in maintenance cost and not suitable for replacement, and leakage hidden dangers exist, the invention provides a novel pointer type oil-level gauge for a transformer. The novel pointer type oil-level gauge is characterized in that an indication cavity is connected with a sealed cavity through a bolt and then connected with a floating ball through a transmission mechanism behind the sealed cavity, and at the same time, the indication cavity and the sealed cavity are connected through a waterproof plug for transmitting data. The device can measure an oil level accurately and is low in cost, easy to replace and not prone to produce leakage, and at the same time, the operation condition is good, and the failure rate is extremely low.

Description

A kind of novel transformer pointer type fuel level indicator

Technical field

The present invention 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 the 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 in recent years development of intelligent grid and intelligent transformer, 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 the oil conservater is delivered to the inside of oil level indicator.Owing to having adopted magnetic coupling technology, fully isolation has guaranteed splendid sealing property inside and outside the oil level indicator, and this also is 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 the back casing and may have the defectives 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 the pollution that also easily causes 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 invention 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, formed by indication chamber, annular seal space and ball float, it is characterized in that: the indication chamber is bolted annular seal space, connect ball float by the gear train behind the annular seal space again, between indication chamber and annular seal space, be connected the transmission of data by waterproof plug simultaneously.

Described a kind of novel transformer pointer type fuel level indicator is 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 is 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 link to each other by waterproof plug.

The invention has the beneficial effects as follows: 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.
