Description
Technical field
The utility model relates to the air pressure monitoring device of gas-break switch in a kind of power equipment.
Background technology
At present, in power equipment, adopt more gas-break switch, for example sulfur hexafluoride breaker, sulfur hexafluoride breaker is to utilize a kind of isolating switch of sulfur hexafluoride (SF6) gas as arc-extinguishing medium and insulating medium.Whether the sulfur hexafluoride gas in sulfur hexafluoride breaker is full is the key factor that is related to isolating switch insulating property, but now also do not have a kind of easy device to remove to detect the air pressure of sulfur hexafluoride gas, can only adopt comparatively complicated equipment to detect, workload is large, operates cumbersome.
Summary of the invention
For solving above technical deficiency, it is a kind of easy to use that the utility model provides, and can detect in real time the air pressure monitoring device of gas-break switch in the power equipment of air pressure.
The utility model is realized by following measures:
The air pressure monitoring device of gas-break switch in a kind of power equipment of the present utility model, comprise with outside
The joint pipeline section of screw thread, described joint pipeline section one end is provided with reducing, the other end is connected with the cylindrical main casing of sealing, in joint pipeline section, be provided with piston, between piston and main casing, be provided with axial spring, piston medial surface is provided with metal contact piece, and metal contact piece two ends have extended axially metal fingertip along joint pipeline section; The main casing surface that is positioned at joint pipeline section is provided with two electrode slices that can contact with two fingertips respectively under spring-compressed state, in described main casing, be provided with button cell, described button cell both positive and negative polarity is connected with two electrode slices respectively, main casing outside surface is embedded with light emitting diode, and described light emitting diode is connected between button cell and electrode slice.
Above-mentioned main casing is provided with solar battery sheet on outer face, and described solar battery sheet is in parallel with button cell.
On above-mentioned main casing excircle, be evenly embedded with several light emitting diodes.
The beneficial effects of the utility model are: can detect in real time the air pressure in gas-break switch, in the time that gaseous tension is normal, can bright light indicate, can find in time the pressure abnormity in gas-break switch, improve the reliability and the security that use.Reduce workload, saved manpower, improved work efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1 joint pipeline section, 2 pistons, 3 metal fingertips, 4 springs, 5 electrode slices, 6 solar battery sheets, 7 light emitting diodes, 8 button cells, 9 main casings.
Embodiment
As shown in Figure 1, the Pressure monitoring of gas-break switch dress in a kind of power equipment of the present utility model
Put, comprise that joint pipeline section 1 can be connected on the inflation inlet of gas-break switch by external thread with externally threaded joint pipeline section 1.Joint pipeline section 1 one end is provided with reducing, the other end is connected with the cylindrical main casing 9 of sealing, in joint pipeline section 1, be provided with piston 2, between piston 2 and main casing 9, be provided with axial spring 4, piston 2 medial surfaces are provided with metal contact piece, and metal contact piece two ends have extended axially metal fingertip 3 along joint pipeline section 1.Reducing can prevent that piston 2 from skidding off from joint pipeline section 1.Main casing 9 surfaces that are positioned at joint pipeline section 1 are provided with two electrode slices 5 that can contact with two fingertips respectively under spring 4 compressive states.If gas-break switch internal gas pressure is enough, under gas pressure, promote piston 2 Compress Springs 4, thereby piston 2 outwards moves along joint pipeline section 1, in the time moving a certain distance, two metal fingertips 3 will contact with electrode slice 5 respectively, thereby have just formed the conductive communication of two electrode slices 5, two metal fingertips 3 and metal contact piece.In the time that air pressure is low, under spring 4 effect, promote piston 2 and move inward, thereby two metal fingertips 3 will disconnect and contacting with electrode slice 5 respectively, two electrode slices 5, two metal fingertips 3 and metal contact piece can not form conductive communication.
In main casing 9, be provided with button cell 8, button cell 8 both positive and negative polarities are connected with two electrode slices 5 respectively, and main casing 9 outside surfaces are embedded with light emitting diode 7, and light emitting diode 7 is connected between button cell 8 and electrode slice 5.In the time of the conductive communication of two electrode slices 5, two metal fingertips 3 and metal contact piece, button cell 8 both positive and negative polarities, two electrode slices 5, two metal fingertips 3, metal contact piece and light emitting diodes 7 have formed closed loop, light emitting diode 7 is shinny, thereby the gaseous tension in prompting gas-break switch is normal, if light emitting diode 7 is not shinny, illustrate that the gaseous tension in gas-break switch is lower, needed make-up gas.
For can continued power, main casing be provided with solar battery sheet 6 on 9 outer faces, and solar battery sheet 6 is in parallel with button cell 8.Solar cell also can be powered, thereby has improved reliability and stability for powering.On main casing 9 excircles, be evenly embedded with several light emitting diodes 7, facilitate observer to observe, also avoid interior light emitting diode 7 to damage the misunderstanding causing.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection domain of this patent.
