THE BACK SIDE CLOSING ABRIDGMENT STYLE DISTRIBUTING BOARD

摘要

The subject innovation is relates to a miniature switchboard rear closed, and more particularly, having an opening and closing door in the front, is provided to one side, the middle and the other side plate is vertically predetermined interval inside, check to form a back to back cabinet and provided plates; And the load break switch which is parallel to the right and left space formed between one side of one side plate and the cabinet of the cabinet disposed so as to face the front of the cabinet; And an arrester which is parallel to the right and left space formed between the side arrangement of the side-plate and the cabinet of the cabinet toward the front of the cabinet in a state located in the lower direction of the load break switch; And right and left in a space formed between the intermediate plate and the one side plate of the cabinet of the cabinet toward the front of the cabinet and arranged in parallel, that the fuse is a fuse holder fixing fitting; And instrument transformer that are parallel to the right and left space formed between the intermediate plate and the other plate of the cabinet toward the front of the switch cabinet layout; And the instrument current transformer is arranged in parallel for the right and left in a space formed between the intermediate plate and the other plate of the cabinet located in the lower direction of the instrument transformers so as to face the front of the cabinet; And the high-pressure vacuum breaker disposed in the space formed between the other side of the other side plate and the cabinet of the cabinet toward the front of the cabinet; The load switches, surge arresters, fuse holders, are each connected instrument transformers, current transformers and high-voltage vacuum circuit breakers for the occasion and for as booth housed inside the cabinet; Relates to a rear closed reduced switchboard comprising the; high-voltage insulators for maintaining the booth above the cabinet at a constant interval. ; The present design is configured as a front of the operator the cabinet because it provided in the interior of the cabinet is high voltage equipment including load switches, surge arresters, fuse holder, instrument transformers, instrument current transformer for and high pressure vacuum circuit breakers and towards the front of the cabinet through the open door provided in the load switches, surge arresters, fuse holder, instrument transformers, instrument current transformers and high-voltage vacuum circuit breakers and are able to more intuitive operation and replacement of high voltage equipment and be easily including the management convenient for sex more not only can be increased may be a greater size reduction than the conventional cabinet, in particular because it is not necessary to be provided with a door for opening and closing the rear of the back of the distribution box provided on the rear surface of the cabinet at the rear of the cabinet open the door there is an effect that can be easily installed in the cabinet than the one also can not be confined to the space that you need a space for closing. ; Distributive boxes, load switches, surge arresters, fuse holder, instrument transformers, current transformers for instruments, high-voltage vacuum circuit breakers, busbars, high-voltage insulators
