Abstract
The utility model relates to a gas insulated switchgear (GIS) partial discharge detection device for a shielding insulation basin. The device comprises a shell and a signal processing board. The signal processing board is arranged on a lower part in the shell, and is connected with a signal leading-out port at the right end of the shell through a signal wire which penetrates through a wire casing. A cover plate is fixed outside the shell through a screw. The shell is connected with the upper part of a hoop through screws on left and right sides at the lower end of the shell. A fixing bolt is arranged on the lower part of the hoop. The device has the advantages that 1, the function of detecting partial discharge in a GIS through a process pouring gate of the shielding insulation basin is realized; 2, the signal processing board is arranged in a metal shielding environment with a sufficient thickness, so that external signal interference is effectively prevented; and 3, the shell has an integral structure, and is only connected with the cover plate in a sealed way, so that the field requirements of moisture resistance and dust tightness are met.
Description
Technical field
The utility model relates to a kind of GIS local discharge detection device of shielding insulation basin.
Background technology
Characteristics such as gas insulated combined electrical equipment (GIS) is little owing to floor area, operational reliability height are used more and more widely.Though the GIS reliability is than higher, the probability of malfunction that operation own possibly occur is lower, in case break down, its destructiveness also is very big, and the loss that accident causes is very big.
Internal fault is more common and be difficult to predict in all kinds of faults of GIS, and internal fault is mainly produced by insulation breakdown.The early stage insulation fault principal mode of GIS is a shelf depreciation; But because GIS structurally is totally enclosed characteristics; Directly detect its failure symptom that possibly occur internally and realize trouble technically; And must be on production link, directly some sensor or other pick-up unit to be installed in GIS inside in GIS producer; These pick-up units itself just possibly be one of reasons that causes fault sometimes, and therefore greatly part producer and GIS user generally do not hope to adopt built-in online detection mode both at home and abroad.
Also there is not at present directly to detect the method that the GIS built-in electrical insulation destroys; What generally adopt is Indirect Detecting Method; Optical detection, chemical constitution detection method, supersonic testing method and UHF Partial Discharge Detection method are generally arranged; But owing to several kinds of fronts or be inappropriate for the not high reason of the validity that is used for online detection of GIS equipment or detection, have only supersonic testing method and UHF Partial Discharge Detection method feasible and effective relatively.
But when using UHF Partial Discharge Detection method; The ambient signal and the various undesired signal of GIS periphery also are exaggerated detection; The pickup electrode major part that obtains is the powerful electromagnetic interference signals of surrounding enviroment, and useful GIS office discharge signal just seem very little very a little less than, all are put GIS office and detect existing patent and technological achievement all is round the technology, the ways and means that above-mentioned detected signal are carried out subsequent treatment; Wherein both comprised and carried out through hardware that signal filtering handles; Also comprise through software and carry out Filtering Processing, but its processing cost that causes thus is very high, and its treatment effect is also undesirable.
The utility model content
The purpose of the utility model provides a kind of gas insulated combined electrical equipment (GIS) local discharge detection device of shielding insulation basin, overcomes the deficiency of above-mentioned aspect in the existing product.
The purpose of the utility model is to realize through following technical scheme:
A kind of GIS local discharge detection device of shielding insulation basin; Comprise housing and signal-processing board; The bottom is provided with signal-processing board in the said housing, and signal-processing board is drawn port through the signal wire that passes the lead-in wire groove with the signal that is arranged on the housing right-hand member and is connected, and hull outside is fixed with cover plate; Housing is connected with anchor ear top, and the anchor ear bottom is provided with set bolt.
The beneficial effect of the utility model is:
1, realized surveying the function of the inner shelf depreciation of GIS through the technology casting gate of shielding insulation basin;
2, signal-processing board places the metallic shield environment of adequate thickness, effectively prevents the external signal interference;
3, housing is an one-piece construction, only is connected with cover plate for sealing, satisfies moistureproof, dustproof field requirement.

Fig. 3 be the described shielding insulation basin of the utility model embodiment the GIS local discharge detection device structural representation two.
Among the figure:
1, housing; 2, signal-processing board; 3, lead-in wire groove; 4, signal is drawn port; 5, cover plate; 6, anchor ear; 7, set bolt.
Embodiment
Shown in Fig. 1-3; The GIS local discharge detection device of the described a kind of shielding insulation basin of the utility model embodiment comprises housing 1 and signal-processing board 2, and the bottom is provided with signal-processing board 2 in the said housing 1; Signal-processing board 2 is drawn port 4 through the signal wire that passes lead-in wire groove 3 with the signal that is arranged on housing 1 right-hand member and is connected; There is cover plate 5 in housing 1 outside through screw retention, and housing 1 is connected with anchor ear 6 tops through the screw of the left and right sides, housing 1 lower end, and anchor ear 6 bottoms are provided with set bolt 7.
When the GIS local discharge detection device of the described shielding insulation basin of the utility model embodiment specifically used, key step was:
1, this device is walked around the shielding insulation basin, tighten anchor ear behind the signal-processing board 2 aligning casting gates is through bolt;
2, keep housing 1 to contact, the casting gate that 2 pairs of realization signal-processing boards will definitely acquired signal with the tight of shielding insulation basin;
3, signal wire is drawn port 4 through lead-in wire grooves 3 from signal from signal-processing board 2 and is drawn.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within the protection domain of the utility model.
