Abstract
Secondary junction box, including the wiring case lid, wiring box and locate the hasp of junction box both sides, the wiring box takes the hasp formula to connect with the wiring case lid. Wiring case lid surface is equipped with the line hole of earth connection. Wiring box bottom is equipped with central entrance hole for insert the external equipment circuit, the bottom is equipped with a rectangle stainless steel aluminum plate, reinforces the terminal box. Junction box bottom both sides are equipped with the secondary connecting row and the fixed control line that gets into the inside instrument and meter of transformer substation of fixed mutual -inductor respectively, and wherein the connecting row is total two sets of and arrange side by side. The junction box bottom is equipped with 2 blow vents. The utility model discloses secondary junction box has adopted stainless steel, can reduce the corruption on surface, has carried out the simplification of certain degree from installation and follow -up work, has guaranteed the reliability service of equipment simultaneously.
Description
Technical field
The utility model relates to a kind of high voltage electric equipment, particularly relates to a kind of secondary connection case.
Background technology
Along with the development of science and technology, electric power resource also makes land used more extensive, thus along with this trend, high voltage electric equipment also starts to appear and reform improvement in a large number in one's mind.Junction box is requisite basic facilities in high voltage electric equipment.Junction box is a kind of switching construction line, marks branched line, is a kind of interface arrangement that wiring and the line inspection are provided convenience.The junction box used at present is the closed secondary connection case adopting iron to make mostly, this junction box is due to the long-time running running environment severe in outdoor, make the corrosion of mutual MWB instrument transformer irony secondary connection case serious, inner sealing lost efficacy and caused case internal wiring terminal by heavy corrosion, had serious potential safety hazard to equipment safety operation.In the prior art, the replacing for junction box is very numerous and diverse, and each replacing all needs to carry out bulk testing to high voltage electric equipment, could drop into new operation.Under the prerequisite not changing casing, can only by processing the parcel of casing outside temporarily, but the not good and inconvenient operation of rainproof effect.
Utility model content
In order to overcome shortcoming and the weak point of background technology, the utility model provides a kind of easy-to-connect, dismounting facility, safe and reliable secondary connection case.
For solving this technical problem, the utility model takes following scheme: a kind of secondary connection case, comprises wiring case lid, wiring casing and be located at the hasp of junction box both sides, and described wiring casing takes buckle type to be connected with wiring case lid; Described wiring casing bottom center is provided with entrance hole, and for accessing external equipment circuit, bottom is provided with the stainless steel aluminium sheet fixed head being installed on bottom incoming hole;
Further, described junction box's cap surface is provided with the string holes of earth connection.
Further, described junction box's two bottom sides is respectively equipped with secondary connection case blow vent.
Further, described junction box's two bottom sides is respectively equipped with secondary connection row and control line, and line bank is two groups and is arranged side by side.
By adopting technique scheme, the beneficial effects of the utility model are: by arranging hasp in casing both sides, make case lid and casing adopt buckle type to be connected, change and originally integrally synthesized non-removable drawback, can change more easily and dismantle; Secondary row wiring is set in casing, can is more stably fixed on instrument transformer, the instrument and meter that control line fixedly can enter transformer station inside is set; Bottom half entrance hole, for accessing external equipment circuit, using stainless steel aluminium sheet butted line box to reinforce, staff directly can be changed in junction box, easier for installation.The utility model secondary connection case have employed the corrosion that stainless steel can reduce surface, has carried out simplification to a certain degree, ensure that the reliability service of equipment simultaneously in installation and follow-up work.
Accompanying drawing explanation
Fig. 1 is the utility model secondary connection box structure figure;
In figure, 1 is ground wire wiring hole, and 2 is wiring case lids, and 3 is secondary connection case hasps, and 4 is secondary connection rows, and 5 is control lines, and 6 is secondary connection case blow vents, and 7 is stainless steel aluminium sheets, and 8 is entrance holes.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Be illustrated in figure 1 the structural representation of the utility model secondary connection case, comprise wiring case lid 1, wiring casing and be located at the hasp 3 of junction box both sides, wiring casing takes buckle type to be connected with wiring case lid, junction box's cap surface is provided with ground wire wiring hole 1, entrance hole is provided with below wiring casing, bottom incoming hole is provided with stainless steel aluminium sheet fixed head, junction box's two bottom sides is respectively equipped with secondary connection row 4 and control line 5, line bank is two groups and is arranged side by side, and junction box's two bottom sides is respectively equipped with secondary connection case blow vent 6.
The installation of the utility model secondary connection case: first, disconnects the measure and control device power supply at operation interval, is removed by the ground wire 1 that junction box top connects.Then remove the set screw of stainless steel aluminium sheet 7 eyelet strip and terminal board bottom case, pull down casing nameplate, install on new casing and pull down terminal board location angle bar, leave a fixed screw.With band, secondary cable is tied again afterwards, remove terminal board, carry out cutting along the back of dotted line in way with hand-held grinder and carry out second time cutting along bottom half.Cut complete, break casing into two with one's hands, pull down set screw from cutting mouth, terminal defecation can be separated with casing.The space that the bottom of secondary connection case is reserved can allow binding post pass at the bottom of case, removes the cable tie before cutting, installs location angle bar and earth connection, secondary wiring terminals row is fixed.Finally with absolute ethyl alcohol, secondary wiring terminals row is cleaned, load onto secondary line threading base plate and carry out shutoff by fire-proof mud.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
