Abstract
The utility model discloses a novel casing pipe mutual inductor which comprises an inner casing pipe, a coil, a current-conducting plate and epoxy resin. The coil is sleeved on the outer side of the inner casing pipe. One end of the inner casing pipe is connected with the current-conducting plate, and the other end of the inner casing pipe is fixedly connected with a baffle. The epoxy resin is used to pour the inner casing pipe, the coil and the current-conducting plate into a whole. One side of the epoxy resin is in a boss structure. A clamping groove and a connection terminal are arranged on the boss. Fixing screw holes are formed below the boss. The coil and the current-conducting plate are externally connected through the connection terminal. The novel casing pipe mutual inductor can effectively avoid the electricity sealing phenomenon caused by illegal operation of a wire end of the inductor, thereby improving accuracy and reliability of measurement.
Description
Technical field
The utility model belongs to the T ﹠ D Technology field, particularly a kind of new casing instrument transformer.
Background technology
At present, outdoor low voltage send electricity, the metering device of its power consumption, comprise three current transformers, by wire the access of electric current and voltage is installed on the outdoor kilowatt-hour meter, but secondary connection screw, pressure-wire and the zero line of instrument transformer all expose, all there is stealing hidden danger in these places.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of new casing instrument transformer for above the deficiencies in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of new casing instrument transformer, comprise inner sleeve, coil, conductive plate and epoxy resin, the inner sleeve outside is arranged with coil, inner sleeve one end is connected with conductive plate, the other end of inner sleeve is fixedly connected with baffle plate, epoxy resin pours into an integrated entity inner sleeve, coil and conductive plate, one side of epoxy resin is boss structure, be provided with draw-in groove and binding post at boss, the boss below is provided with fixing threaded hole, and coil and conductive plate are external by binding post.
Described conductive plate is provided with plug hole and center hole, is provided with fixed card slot in the conductive plate lower surface.
Described conductive plate is made by metallic copper.
The utility model compared with prior art can effectively be avoided the instrument transformer lead end is carried out the stealing electrical phenomena that illegal operation causes, thereby improves the characteristics of measurement accuracy and reliability.
