Abstract
The invention provides a current transformer cabling channel in a high-voltage switch cabinet, and relates to the technical field of whole sets of high-voltage distribution equipment. The current transformer cabling channel comprises a current transformer installing beam which is fixed in the switch cabinet, a current transformer is installed on the current transformer installing beam, and a cabling channel body is formed inside the current transformer installing beam. A channel cover plate is connected to the front end face of the current transformer installing beam and can cover the current transformer installing beam and the cabling channel body in the current transformer installing beam. Outlet holes are formed in the upper end face of the current transformer installing beam at intervals. Inlet holes are formed in the rear side face of the current transformer installing beam. Leads of the current transformer are led into the cabling channel body from the inlet holes, lead bodies are arranged in the cabling channel body, lead heads of the leads are led out of the outlet holes, and therefore the leads can be protected from damage in the cabling channel, and the service life of the leads is prolonged.
Description
Technical field
The present invention relates to high pressure complete set of distribution technical field, be specifically related to current transformer trough in a kind of high-tension switch cabinet.
Background technology
High-tension switch cabinet belongs to high voltage distribution installation, is mainly used in power plant, the power transmission of medium and small generator, the electric power system secondary substation be subject to electricity, power transmission, the distribution of industrial and mineral enterprises and institutions, and the starting of Large-scale High-Pressure motor etc., be widely used important controller switching equipment in electric power system.Generally all be provided with a plurality of current transformers in existing high-tension switch cabinet, and current transformer is all generally to be fixed on a mounting rail, the lead-in wire of current transformer just directly is bundled on mounting rail, and lead-in wire of long duration is easily aging, cause security incident, and wiring is also inconvenient.
Summary of the invention
Technical problem to be solved by this invention is to provide current transformer trough in high-tension switch cabinet a kind of simple in structure, reasonable in design.
Technical problem to be solved by this invention realizes by the following technical solutions:
Current transformer trough in a kind of high-tension switch cabinet, comprise that one is fixed on the current transformer mounting rail in switch cubicle, on described current transformer mounting rail, current transformer is installed, described current transformer mounting rail inside is provided with trough, the front end face of described current transformer mounting rail is connected with slot cover plate, this slot cover plate can cover on the current transformer mounting rail, trough in the current transformer mounting rail is covered, be interval with wire hole on the upper surface of described current transformer mounting rail, the trailing flank of described current transformer mounting rail is provided with entrance hole, the lead-in wire of current transformer is incorporated into trough from entrance hole, the main body that will go between is placed in trough, the end of a thread of lead-in wire is drawn out to outside from wire hole, pilot protection can be damaged in trough like this, improve the useful life that goes between.
In described wire hole, cable cover(ing) is installed, for the protection of lead-in wire.
The quantity of described wire hole is identical with the quantity of current transformer, has how many current transformers just to offer how many wire holes, and each current transformer uses separately a wire hole, facilitates wiring.
Described slot cover plate is fastened on the current transformer mounting rail.
The invention has the beneficial effects as follows: the present invention is simple in structure, and modern design arranges cable in online box; can effectively protect cable not to be damaged, improve the useful life of cable, guarantee the long-term security operation of switch cubicle; have good actual application value, market potential is large, good in economic efficiency.
