Description
Technical field
Metal bellow oil conservator is the utility model is related to, specifically a kind of outer oil with automatic protection functions is vertical
Metal bellow oil conservator.
Background technology
At present, the metal bellow oil conservator used in oil-immersed type power coordinative composition of equipments, oil is compensated by expansion or shrinkage
The change of volume.Existing metal bellow oil conservator, can not be in the case of pressure rise to oil conservater when reaching capacity
Protection is formed, oil conservater damage is often resulted in, had both reduced the service life of oil conservater, and added production cost again.
Utility model content
In order to solve the problems, such as not protecting oil conservater in the case of pressure rise, the purpose of this utility model is to carry
For a kind of outer oily vertical metal bellow oil conservator with automatic protection functions.
The purpose of this utility model is achieved through the following technical solutions：
The utility model includes cabinet and the wavy metal compensation body in the cabinet, the wavy metal compensate body
The top being installed in cabinet, exhaling for wavy metal compensation body breathing when the top of wavy metal compensation body is provided with operation
Suction pipe, the expansion space of body is compensated between the bottom of the wavy metal compensation body and the bottom surface of the cabinet for wavy metal；
The cabinet is tightly connected by the pipeline road that bottom connects and oil tank of transformer, and the cabinet, which is provided with, to be used to discharge in cabinet
The gas exhaust piping of portion's gas；Limit travel switch is installed, the bottom of cabinet is provided with drainage device, institute in the side wall of the cabinet
State limit travel switch and drainage device is electrically connected with the controller respectively；
Wherein：The drainage device includes drain line and gate gurgle valve, and the drain line is communicated in the bottom of the cabinet,
The gate gurgle valve is arranged on drain line, and is electrically connected with the controller；In the upper end and cabinet of the gas exhaust piping
Top is connected, and lower end is stretched out by the bottom of the cabinet；The wavy metal compensation body does longitudinally perpendicular motion in cabinet,
Moved along the short transverse of oil conservater.
The advantages of the utility model is with good effect：
The utility model is provided with limit travel on cabinet and switched, and is mounted with drainage device in bottom of cabinet bulk, avoids
Wavy metal compensation body damages in hypertonia, extends the service life of wavy metal compensation body.
Brief description of the drawings
Fig. 1 is internal structure schematic diagram of the present utility model；
Wherein：1 is gas exhaust piping, and 2 be that limit travel switchs, and 3 be cabinet, and 4 be pipeline road, and 5 be drainage device, and 6 are
Wavy metal compensates body, and 7 be respiratory siphon, and 8 be gate gurgle valve, and 9 be drain line.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model includes cabinet 3 and the wavy metal compensation body 6 in the cabinet 3, wherein
Wavy metal compensation body 6 is installed on the top in cabinet 3, and the top of wavy metal compensation body 6 is provided with respiratory siphon 7, for transporting
Wavy metal compensation body breathing during row, body is compensated for wavy metal between the bottom of wavy metal compensation body 6 and the bottom surface of cabinet 3
Expansion space.Cabinet 3 is tightly connected by the pipeline road 4 that bottom connects and oil tank of transformer, is formed with this really complete
Sealing oil circuit system.Wavy metal compensation body 6 does longitudinally perpendicular motion in cabinet 3, i.e., is moved along the short transverse of oil conservater.
Cabinet 3 is provided with gas exhaust piping 1, and the upper end of the gas exhaust piping 1 is connected with the top in cabinet 3, and lower end is by cabinet
The bottom of body 3 is stretched out, for discharging the gas inside cabinet 3.
Limit travel switch 2 is installed, the bottom of cabinet 3 is provided with drainage device 5 in the side wall of cabinet 3.Drainage device 5 wraps
Drain line 9 and gate gurgle valve 8 are included, the drain line 9 is communicated in the bottom of cabinet 3, and gate gurgle valve 8 is arranged on drain line 9, and
It is electrically connected with the controller respectively with limit travel switch 2.
Operation principle of the present utility model is：
When transformer oil temperature rise, transformer oil is entered in cabinet 3 by pipeline road 4, and wavy metal compensation body 6 is done
Longitudinally perpendicular motion, the gas that wavy metal is compensated in body 6 are discharged to air, and wavy metal compensation body 6 shrinks.Work as transformer
When oil temperature reduces, the transformer oil in cabinet 3 flows back to transformer by pipeline road 4, and gas enters wavy metal compensation body 6,
Wavy metal compensation body 6 expands, and carrys out the change of compensator transformer oil volume with the change of volume.
When oil conservater reaches capacity, signal is passed to controller, controller control gate gurgle valve 8 by limit travel switch 2
Open march draining.When less than limit position, controller controls gate gurgle valve 8 to close again, so as to protect wavy metal to compensate
Also body 6 is without damage.
