Description
Technical field
The invention belongs to electric switch switch board field, particularly to integrated board-like heavy-current control cabinet.
Background technology
It is currently used for the regulator cubicle of technical grade, usually using cabinet, electrical equipment is put together, cabinet is typically outside to be
Common square cabinet, guide rail and installing plate are installed in internal setting, when electrical equipment is more, can also be installed using multilayer
Guide rail；In conventional electrical switch switch board field, because switch board space constraints and national standard acceptance specification require, for side
Just wiring, the arrangement of electrical equipment is very sparse so that the space availability ratio of electrical control cabinet is relatively low.
Electrical equipment in regulator cubicle is attached realizing the purpose of electrical control by electric wire, currently uses regulator cubicle and enters
When row wiring, need the trend of line style, line color, wire size and line to be selected and is arranged, and installation process is also
Repeatedly to verify whether electric wire installs fastening, a set of electrical equipment installation needs relatively complicated step；Wiring is caused to imitate
Rate is low.
What electric wire had now is also directly exposed in regulator cubicle, there are a lot of heater elements, this just leads in electrical control cabinet
Cause electrical control cabinet internal temperature higher so that the electric wire insulation layer exposing is easy to aging, or even cause short circuit between electric wire
Phenomenon.In order to prevent electric wire directly exposed in regulator cubicle, now also in regulator cubicle install wire casing, but the installation of wire casing is no
Doubting causes loaded down with trivial details wiring task more loaded down with trivial details.
Electrical control cabinet has to bring all instrument (for example: be cut, the instrument such as spanner) in maintenance, and maintenance is all necessary every time
Electric equipment is unloaded, wastes time and energy, body of operationally sometimes must also squatting down, proceed to inside cabinet, operation is not very square
Just, the inside circuit is many, and operator enters and easily causes very much electric shock, affects personal safety；Cause inconvenience and the insulation division of malfunction elimination
The progressive damage of position, may lead to the generation of short circuit accident.
