Description
Technical field
This utility model relates to outlet box, is specifically related to a kind of secondary lead wires outlet box.
Background technology
The outlet box of transformer is a kind of transformer auxiliary device being connected on transformer casing, is mainly used in connecting the high tension cable directly driving transformer work, thus requires have higher waterproof and dustproof performance.Due in some special occasions, transformer needs reversely, even to stand upside down installation, thus requires that outlet box has good water resistance in a plurality of directions.Current transformer outlet box generally adds sealing filler ring at the joint of cassette holder Yu lid, but such outlet box sealing property just depends entirely on the performance of seal washer, once seal washer is aging because of colding and heat succeed each other, its water resistance will be substantially reduced, outlet box also can lose water resistance, and the safe operation to transformer causes potential threat.
At present, conventional transformer outlet box is the case structure without drainage arrangement.Transformer is in use, the most out of doors in environment, the situations such as outlet box inevitably deforms, ftractures, inner seal aged deterioration, therefore when transformer works under excessive moisture, the working environment drenched with rain, it is possible that the internal hydrops of outlet box is more, transformer cannot normally work, situation about even damaging.Meanwhile, existing transformer outlet box also there will be heating, internal temperature crosses high situation, causes the wire in outlet box to burn out, and brings potential safety hazard also can to the normal work of transformer.
At notification number CN103516115A, date of declaration be on January 15th, 2014 patent of invention in disclose a kind of outlet box using general structure outlet cover plate, including junction box seat, at rosette wire hole, it is bolted outlet cover plate, outlet cover plate connects locking swivel nut；Described outlet cover plate is respectively provided on two sides with two outlet cover plate connecting holes, two outlet cover plate connecting hole distributions symmetrical above and below；Several outlet cover plate wire holes it are provided with in the middle part of outlet cover plate.This universal outlet box need not change the size of junction box seat, only changes the size of outlet box cover plate, it is possible to meet motor various outlet demand, improve versatility.But this outlet box uses the potted components such as sealing gasket to ensure the sealing property of whole outlet box, there will be the situations such as sealing gasket is aging the most unavoidably, the most whole outlet box the most just loses sealing water resistance, when outlet box inner inlet, can damage motor；Meanwhile, when there are the problems such as short circuit, power not coupling, wire can produce substantial amounts of heat, brings bigger potential safety hazard；Additionally, there is no current sensing means inside this outlet box, if electrician operates without power-off, it may occur that bigger security incident.

Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.Obviously, described embodiment is a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullA kind of secondary lead wires outlet box，2 are renovated including junction box seat 1 and the sealing that coordinates with junction box seat 1，Junction box seat 1 is rounded，The both sides of junction box seat 1 are equipped with discharge outlet 14，Discharge outlet 14 is provided with automatic drain valve 15，Junction box seat 1 is internal is provided with at least two binding post 6，Binding post 6 is provided with fixed screw 7，Fixed screw 7 top surface is provided with electro-insulating rubber layer 8，Junction box seat 1 bottom is provided with incoming line 3，Junction box seat 1 top is provided with line outlet 4，Incoming line 3、Line outlet 4 is internal is equipped with inflatable rubber ring 5，Inserting slot 9 it is provided with between incoming line 3 and binding post 6，Inserting slot 9 is provided with fastp-acting fuse 10，Wire casing 11 it is provided with between line outlet 4 and binding post 6，Upper wire casing 11 is provided with current sensing means 12，Current sensing means 12 connects warning lamp 13，Fastp-acting fuse 10 and current sensing means 12 are equipped with waterproof case.
During use, circular joint box seat 1 being first fixed on relevant position, junction box seat 1 is rounded can effectively reduce occupied area.The wire of transformer driving means or simulation transformer device is penetrated from incoming line 3, and is fixed in inserting slot 9；Again transformer wire is penetrated from line outlet 4, and be fixed in wire casing 11；Unscrewing fixed screw 7, be fixed on binding post 6 by the wire in inserting slot 9 and upper wire casing 11, the electro-insulating rubber layer 8 of fixed screw 7 top surface can effectively prevent operator's non-power-off to be electrically shocked wound when operating.Inflating toward the inflatable rubber ring 5 within incoming line 3 and line outlet 4, the wire in incoming line 3 and line outlet 4 can be wrapped by inflatable rubber ring 5, it is ensured that whole outlet box has good sealing water resistance.Finally sealing is renovated 2 to cover and i.e. install.
When installing or keep in repair, the current sensing means 12 on upper wire casing 11 can detect so that the wire at pair of wire connection terminals 6 two ends is the most charged, and when circuit is charged, the warning lamp 13 being connected with current sensing means 12 can light, and warning operator's circuit is charged.When water inlet in outlet box, the automatic drain valve 15 of junction box seat 1 both sides can be opened, hydrops in outlet box can be discharged from discharge outlet 14, can recover the normal work of transformer at short notice, the waterproof case of fastp-acting fuse 10 and current sensing means 12 is prevented from fuse 10 and current sensing means 12 is immersed in water.When there is short circuit and the problem such as power not coupling, in outlet box, circuit can transship heating, and now fused wire understood by the fastp-acting fuse 10 on inserting slot 9, it is to avoid transformer is damaged.
A kind of secondary lead wires outlet box provided by the utility model can line disconnection drain rapidly the hydrops in outlet box after outlet box is intake, recover normally working of transformer at short notice；Outlet box wiring is short and sweet, it is simple to installs and keeps in repair；Additionally it is possible to warning operator's circuit is the most charged, occur with being prevented effectively from security incident.
Above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, and the essence of appropriate technical solution can not be made to depart from the spirit and scope of this utility model each embodiment technical scheme.
