Abstract
The utility model belongs to high-voltage electrical equipment field, and especially a kind of SF6 sensor protecting case, be made up of sensor housing and dust-proof mesh enclosure, sensor housing has probe hole, probe hole is provided with O-ring seal, dust-proof mesh enclosure is located on probe hole.SF6 sensor protecting case of the present utility model; adopt two-piece design; after probe is put into sensor housing, the circuit module portion of probe is just in sealing state, plays the effect of dust and moisture; probe is in dust cover; more be vented in air contact more abundant, more the SF6 leaked in air can be detected in rugged surroundings, ensure that its accuracy detected; dust cover also well can protect probe, extends the serviceable life of SF6 sensor and the accuracy of measurement greatly.
Description
Technical field
The utility model belongs to high-voltage electrical equipment field, especially a kind of SF6 sensor protecting case.
Background technology
SF6(sulfur hexafluoride) gas owing to having fabulous insulating property and arc extinction performance, obtain in electric system and apply widely.But the leakage of SF6 gas then can pollute indoor environment, make to enter the operating personnel in room, make an inspection tour the health of maintainer even life be subject to serious threat.Therefore, good SF6 gas leakage monitoring technology is subject to attention and the pursuit of power industry practitioner.
Current SF6 probe great majority are used to the detection to SF6 Leakage Gas in transformer station, analysis can be detected in real time when the SF6 gas content in environment exceeds standard, then report to the police, the object of the normal operation can also guaranteeing equipment that can not only guarantee personal safety, so the sensitivity of probe is very important.But supply line comprises terminal change, community becomes, centre becomes; each link of installing the power supply facilitiess such as transformer all needs the leak detection carrying out SF6; and in community becomes; equipment installation environment can not show a candle to transformer station, and in community becomes, SF6 probe is generally contained in cable duct, and environment is dark moist; dust is also many; have a strong impact on the sensitivity of probe, brought hidden danger to safety, need to redesign special SF6 sensor protecting case for this situation with this.
Summary of the invention
Of the present utility modelly aim to provide that a kind of structure is simple, reliability is strong, be applicable to the SF6 sensor protecting case of complex environment.
SF6 sensor protecting case of the present utility model, be made up of sensor housing and dust-proof mesh enclosure, sensor housing has probe hole, probe hole is provided with O-ring seal, dust-proof mesh enclosure is located on probe hole.
Above-mentioned SF6 sensor protecting case, described dust-proof mesh enclosure vertical plane is provided with shutter.
Above-mentioned SF6 sensor protecting case, described sensor housing is also provided with power signal line.
The utility model has following beneficial effect.
1, SF6 sensor protecting case of the present utility model; adopt two-piece design; after probe is put into sensor housing, the circuit module portion of probe is just in sealing state, plays the effect of dust and moisture; probe is in dust cover; more be vented in air contact more abundant, more the SF6 leaked in air can be detected in rugged surroundings, ensure that its accuracy detected; dust cover also well can protect probe, extends the serviceable life of SF6 sensor and the accuracy of measurement greatly.
2, the utility model is provided with shutter on dust-proof mesh enclosure vertical plane, when using in the presence of a harsh environment, even if when dust accumulation is more, the shutter of side also can ensure the detection sensitivity of sensor probe, guarantee that, under dangerous situation, sensor still can normally work.
3, reserved power signal line on sensor housing, product structure design is reasonable, guarantees the sealing of housing itself, non-maintaining after one-step installation.
Accompanying drawing explanation
Fig. 1 is SF6 sensor protecting case one-piece construction schematic diagram of the present utility model.
Fig. 2 is sensor housing structure schematic diagram.
Fig. 3 is dust-proof mesh enclosure structural representation.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described.
As shown in Figure 1; SF6 sensor protecting case of the present utility model; adopt two-piece design; be made up of sensor housing 1 and dust-proof mesh enclosure 2; sensor housing 1 is for the circuit part of mode SF6 sensor; adopt completely airtight design, there is some strength, can ensure that the electronic component of sensor internal is clean dry.Sensor housing 1 has probe hole 3, probe hole 3 is provided with O-ring seal 4, dust-proof mesh enclosure 2 is located on probe hole 3.
Fig. 2 is the utility model sensor housing 1 structural representation, and sensor housing is also provided with power signal line 5.Fig. 3 is dust-proof mesh enclosure 2 structural representation, in figure dust-proof mesh enclosure 2 sidewall on be provided with window shutter.
What the utility model gave a kind of concrete variable position is fixedly connected with mode; but should see; the fixed form that in this area, relative position is adjustable is a variety of in addition; every technological thought according to this patent; other equivalent modes on this technical scheme basis; within the protection domain all falling into this patent, the technology do not related in this patent is all realized by prior art.
