Abstract
The utility model discloses a fuse chamber structure which comprises an installation cylinder and a moveable cover. A fuse cylinder is internally provided with a cavity with an opened end. The moveable cover is movably clamped with the installation cylinder. Two insulating pieces are arranged on the installation cylinder. Each of the insulating pieces is provided with a conductive piece. The two conductive pieces extend into the both ends of the installation cylinder and are respectively connected with a permanent seat at one end of the installation cylinder and a conductor on at the other end of the moveable cover. The permanent seat is provided with a disc provided with an installation hole. A conductive bolt passes through the installation hole to fix the disc inside the cavity. A compressing piece is arranged on the circumference of the disc. The compressing piece extends out downward obliquely and then stretches upward obliquely to form a concave bending. A ring type tension spring is sleeved on the bending to hoop the compressing piece. One end of a fuse core extends into a ring formed by the compressing piece and is connected with the conductive piece through the conductive bolt and compressed and fixed by the compressing piece. The structure of the fuse chamber is simple and compact in structure, is convenient to change the fuse core and improves the changing efficiency of working personnel.
Description
Technical field
The utility model relates to a kind of fuse chamber.
Background technology
On the Operation and Maintenance of all kinds of switchgears,, be integrated with air chamber because the fuse chamber is arranged in the air chamber mostly.This structure is not very reliable, and it is inconvenient to change fusible core, the fuse obscission usually takes place, even fusible core is broken, and causes the damage of switchgear, reduces product useful life.
The utility model content
The purpose of the utility model provides a kind of replacing fusible core fuse cell structure easily.
To achieve these goals, adopt following technical scheme: a kind of fuse cell structure comprises installation tube and removable cover; Be provided with the cavity of an end opening in the fusing tube, removable cover and installation tube activity clamping, two insulating parts are arranged on the installation tube; Be provided with conducting strip in each insulating part, two conducting strips stretch into the two ends of installation tube, respectively with the removable cover of the holder of installation tube one end and the other end on electric conductor join; It is characterized in that: said holder comprises the disk with installing hole, and conducting bolt passes installing hole disk is fixed in the cavity inboard, and the circumference of disk is provided with clamping piece; Clamping piece after stretch out the declivity below, extends to oblique upper earlier again, forms a concave shaped bending; The extension spring of circle formula is enclosed within the bending, with the clamping piece banding; One end of fusible core stretches in the ring of clamping piece composition, join through conducting bolt and conducting strip, and compacted is fixed;
The inboard of removable cover is provided with the U-shaped collar of opening towards cavity inside; Bending on one side direction of the U-shaped collar contacts with conducting strip, the downward bending of opposite side; Contact with fusible core; The annular cushion block is inserted in the U-shaped collar, and cushion block is fixed through the inwall of bolt and removable cover, and fusible core and removable cover are fixed in the hole that clamping screw passes on the cushion block.
