Abstract
The utility model discloses an outdoor SF6 density relay rainproof device. The outdoor SF6 density relay rainproof device comprises a cover body 1 and a bottom board 2; the bottom board 2 is connected with the cover body 1 through a connecting mechanism; the connecting mechanism is screw connection; and the cover body is an inclined structure with a higher rear part and a lower front part. The outdoor SF6 density relay rainproof device of the utility model covers a gauge outfit of an outdoor SF6 density relay, and an M6-bolt hole and a secondary wiring terminal are completely covered by the outdoor SF6 density relay rainproof device directly; the cover body which is an inclined structure with a higher rear part and a lower front part can well solve the problem of flow direction of water, thereby facilitating drainage; and therefore, the problem that the outdoor SF6 density relay and a secondary wiring box are damped because of inflowing of the water can be solved. Thus, the reliability of the operation of equipment can be improved. The outdoor SF6 density relay rainproof device is advantageous in simple design, convenient manufacture, low cost as well as economic and practical properties. With such a small device, serious problems can be solved.
Description
Technical field
The utility model belongs to Power system security control relay auxiliary protection technical field, is specifically related to a kind of outdoor SF6 density monitor rain insensitive device.
Background technology
The SF6 density monitor is used for monitoring the inner SF6 gas pressure of SF6 apparatus body.Because SF6 gas has good insulation and arc extinguishing ability, therefore be widely used in the high-voltage electrical equipment, top design at SF6 density monitor shell has a straight open to atmosphere hole, this hole needs to use the bolt of M6 by the sealing gasket good seal in the equipment conveying process, prevent that the damping oil that SF6 density monitor inside is filled from leaking, but behind the rigging up and debugging end-of-job, preparation is sent before the electricity, then need the bolt of this M6 is unscrewed, guarantee that SF6 density monitor inside communicates with atmosphere, requirement is the certainty of measurement in order to ensure the SF6 density monitor like this.Owing to need when equipment normally moves this M6 bolt is unscrewed, guarantee that SF6 density monitor inside communicates with atmosphere, it is inner that airborne like this moisture and rainwater can enter into by the bolt hole of M6 the SF6 density monitor, cause the corrosion of SF6 density monitor internal component, finally cause SF6 density monitor pointer indication distortion.A kind of closure casing of electric instrument is disclosed in CN 202177640 U, comprise terminal in-out end, enclosed metal shell, control panel and plate draw-in groove, control panel is installed in respectively the relative both sides of metal shell with the binding post manhole appendix, the plate draw-in groove is fixed on metal shell inside in pairs, and the position of described one-tenth plate draw-in groove lays respectively at the both sides at control panel and binding post manhole appendix place.It is with plastic housing structural reform metal shell of the prior art, metal shell seals on four sides, electronic instrument is arranged in the utility model closure casing, reached the specific (special) requirements of waterproof and dustproof, anti-EMC4 level static, metal shell also is conducive to heat radiation, effectively solved the plate heat dissipation problem of electric instrument, satisfied the safe handling of electric instrument under the special occasions, but its cost of manufacture is high, loading and unloading are inconvenient, so need a kind of simple in structure, cheap, convenient disassembly and rainproof effective device.
The utility model content
That the purpose of this utility model is to provide is a kind of simple in structure, cheap, the outdoor SF6 density monitor rain insensitive device of convenient disassembly.
Realize that the technical scheme that the purpose of this utility model adopts is: a kind of outdoor SF6 density monitor rain insensitive device, comprise cover body and base plate, base plate is connected bindiny mechanism with cover body and connects.
Described bindiny mechanism is for being threaded.
Described cover body is the front low dip shape of rear height.
The utility model covers on the gauge outfit of outdoor SF6 density monitor, directly the bolt hole of M6 and secondary wiring terminals are all covered, with regard to having solved well the problem of outdoor SF6 density monitor and secondary terminal box watered and wetting, improved the equipment reliability of operation like this.This open air SF6 density monitor rain insensitive device simplicity of design, easy to make, with low cost, economical and practical, little making solves large problem.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1: a kind of outdoor SF6 density monitor rain insensitive device, comprise cover body 1 and base plate 2, base plate 2 is connected with cover body and is connected by bindiny mechanism.Described bindiny mechanism is for being threaded.Described cover body is the front low dip shape of rear height.The utility model covers on the gauge outfit of outdoor SF6 density monitor, directly the bolt hole of M6 and secondary wiring terminals are all covered, and the low fine problem that solves current direction before high behind the cover body, make things convenient for draining, so just solved well the problem of outdoor SF6 density monitor and secondary terminal box watered and wetting.Improved the equipment reliability of operation.This open air SF6 density monitor rain insensitive device simplicity of design, easy to make, with low cost, economical and practical, little making solves large problem.
Claims (3)
1. outdoor SF6 density monitor rain insensitive device, it is characterized in that: comprise cover body and base plate, base plate is connected bindiny mechanism with cover body and connects.
2. described outdoor SF6 density monitor rain insensitive device according to claim 1, it is characterized in that: described bindiny mechanism is for being threaded.
