Abstract

The utility model relates to a safety detecting device for power facilities, and particularly to an oil level indicator of a transformer, which includes a bypass, a floating ball, a trigger switch and a switch loop, wherein the bypass is communicated with the bottom part of a transformer oil tank; the pipe diameter of the bypass is gradually decreased in thickness from top to bottom; the floating ball is arranged behind the bypass; the trigger switch is arranged at the lowest limiting position of the transformer oil in the bypass; the trigger switch is connected with the switch loop; the floating ball is conductive; the diameter of the floating ball is identical with that at the lowest limiting position of the transformer oil in the bypass; and an audible and visual alarm is arranged on the switch loop. The utility model has the advantages that the residue of the transformer oil can be monitored in real time, and the audible and visual alarm can be used for reporting the working staff, so as to save the labor.

Description

A kind of transformer oil level indicator
Technical field
The utility model relates to electric power facility and uses safety detection device, relates in particular to a kind of transformer oil level indicator.
Background technology
In the use of transformer; The volume of the transformer oil of using owing to transformer can change along with variation of temperature, has just determined, along with variation of temperature; Oil level in the transformer changes phenomenon greatly; When oil level is too high or too low, just have the generation of potential safety hazard, send the special messenger to monitor in real time and waste of manpower, the utility model just provides a kind of device that oil level in the transformer is detected in real time and reports to the police.
The utility model content
The purpose of the utility model just provides a kind of device that can monitor the interior oil level of transformer automatically and can report to the police in good time.
The utility model comprises bypass, ball float, trigger switch and switch loop, and bypass and oil tank of transformer bottom is communicated with, bypass from top to bottom caliber by slightly to thin variation; Place ball float in the bypass; The minimum spacing place of transformer oil is provided with trigger switch in the bypass, and trigger switch links to each other with the switch loop, but wherein ball float is the ball float of conductive material; The equal diameters at the minimum spacing height place of transformer oil in floating ball diameter and the bypass, the switch loop is provided with sound and light alarm.
Sound and light alarm has been installed in series on the switch loop of the utility model.
The advantage of the utility model is to monitor in real time the surplus of transformer oil, and informs the staff and save workman's work through sound and light alarm.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation:
Fig. 1 is the working state schematic representation of the utility model.
Embodiment
As shown in Figure 1; The utility model comprises bypass 5, ball float 4, trigger switch 6 and switch loop 3, and bypass 5 is communicated with oil tank of transformer 1 bottom, bypass 5 from top to bottom caliber by slightly to thin variation; Place ball float 4 in the bypass 5; The minimum spacing place of transformer oil is provided with trigger switch 6 in the bypass 5, and trigger switch 6 links to each other with switch loop 3, but wherein ball float 4 is the ball float of conductive material; The equal diameters at the minimum spacing height place of transformer oil in floating ball diameter and the bypass 5, switch loop 3 is provided with sound and light alarm.
Sound and light alarm has been installed in series on the switch loop 3 of the utility model.
Among Fig. 12 is transformer oil, and bypass 5 constitutes linker with oil tank of transformer 1, and the interior innage of the innage in the bypass and oil tank of transformer is identical; Since bypass from top to bottom caliber by slightly to thin variation; Minimum spacing height place at transformer oil is provided with trigger switch 6, and when oil mass arrives minimumly when spacing less, ball float 4 just is stuck in minimum spacing height; The conducting in trigger switch loop 3; Thereby under the drive of power supply 8, acoustic-optic alarm begins to report to the police, and the prompting staff pays close attention to oil level and takes corresponding measure that equipment is protected.
The equal diameters at the minimum spacing height place of transformer oil in the floating ball diameter of the ball float in the utility model and the bypass 5; The size of trigger switch 6 itself is very thin; If trigger switch 6 adopt thickness bigger, so, the diameter of ball float adds that the thickness of trigger switch equals the diameter at minimum spacing height place; Guarantee can directly not drop to too for a short time to be lower than the effect that the minimum bit position loses warning, or be snapped to the effect of not going to lose warning under the minimum bit position that is higher than too greatly.

Claims (2)

1. transformer oil level indicator; It is characterized in that: said transformer oil level indicator comprises bypass (5), ball float (4), trigger switch (6) and switch loop (3); Bypass (5) is communicated with oil tank of transformer (1) bottom; Bypass (5) from top to bottom caliber by slightly to thin variation, place ball float (4) in the bypass (5), the minimum spacing place of the interior transformer oil of bypass (5) is provided with trigger switch (6); Trigger switch (6) links to each other with switch loop (3); Wherein ball float (4) but be the ball float of conductive material, the equal diameters at the minimum spacing height place of the interior transformer oil of floating ball diameter and bypass (5), switch loop (3) are provided with sound and light alarm.
2. a kind of transformer oil level indicator as claimed in claim 1 is characterized in that: sound and light alarm has been installed in series on the said switch loop (3).
