Abstract

The utility model provides a junction box used for a secondary junction of a mutual inductor. According to the junction box, doubling is achieved in a mode that secondary lines penetrate through pressing holes and are screwed up by screws, and therefore the reliability of doubling is guaranteed. Terminals are separated by baffles, the safety of doubling is guaranteed, and a multipoint pressing manner is adopted for sealing grooves, and therefore sealing performance is guaranteed.

Description

Instrument transformer novel secondary terminal box
Technical field
The utility model relates to novel sensor terminal box.
Background technology
At present, the tradition instrument transformer all is the martingale of adopting little porcelain vase with secondary connection, the mode that the bolt double end is fastening that the little porcelain vase mode of connection adopts, impetus only has one, and on the cover board can existing repeatedly, sealing increases unstable factor, little porcelain vase wiring needs the secondary connection head is bent to the circular wiring more bigger than the secondary terminals on the little porcelain vase, the mode of circular rings wiring is expressed to line in the process that compresses easily and causes contact insufficient outside the contact-making surface, perhaps adopt the mode of connection of binding post, the binding post exposed part is oversize, be in contact with one another easily and cause short circuit, owing to be subjected to the impact of traditional wired mode, be the production length consuming time of instrument transformer, it is many to take a lot of work, yield poorly.
The utility model content
In order to address these problems, increase work efficiency and adopt the whole terminal box of combination transformer secondary, adopt this terminal box not only to reduce terminal box and think the airtight bad risk of casing, and the secondary line mode of connection is simple, reliable, easy to operate, increase between the secondary joint and cut off, prevent short circuit, saved like this secondary terminal box installation time, improved operating efficiency.
The technical scheme that the invention for solving the technical problem is taked is: secondary joint doubling mode adopts direct perforation, with the mode of screw in compression; Sealing means adopts Gask-O-Seal, and sealing gasket embeds in the terminal box sealed groove, and the sealing pressing tieholen is evenly distributed on the sealed groove, makes it when bearing pressure, and pressure can be evenly distributed on the sealing gasket.Prevent that the short circuit mode from adopting dividing plate partition of employing between each secondary joint, prevents that its contact from causing short circuit.
Originally make practical beneficial effect:
Doubling makes its doubling contact-making surface reliable by direct perforation with the mode of screw in compression, and is difficult for looseningly, and high efficiency simple to operate has avoided the binding post exposed part oversize, causes to be in contact with one another short circuit; Adopt in the sealing strip embedding sealing groove, and the mode of equally distributed sealing pressing tieholen once compresses, it is even to compress like this distribution of force, and good sealing effect is avoided repeatedly compressing the numerous unfavorable factor that compresses with a point and caused poorly sealed accident to occur.
Description of drawings:
Fig. 1 is the novel schematic diagram of this use
Among Fig. 1,1, upper collet threaded, 2, the sealing pressing tieholen, 3, upper doubling hole, 4, division board, 5, lower collet threaded, 6, lower doubling hole, 7, sealed groove.
Embodiment
By the phase order relation secondary line is put into lower doubling hole (6), then with screw from lower collet threaded (5), be screwed into and compress.The secondary loop wire that wiring is used is put into upper doubling hole (3), then with screw from upper collet threaded (1), be screwed into and compress, secondary loop wire separates by division board (4).Sealing ring is put into and bolt is put into all sealing pressing tieholens (7) behind the sealed groove (7) and be screwed into and compress.

Claims (2)

1. a terminal box that is used for mutual inductor secondary connection is characterized in that the doubling of boring a hole, and uses screw in compression, and sealing strip embedding sealing groove is again by equally distributed screw screw in compression.
2. a kind of terminal box for mutual inductor secondary connection according to claim 1 is characterized in that division board is arranged between the binding post.
