Abstract
Provided by the utility model is a switch cabinet with small copper bar connecting lines. The switch cabinet comprises a switch cabinet box body, installation frames, electronic components and a main bus. The installation frames are arranged inside the switch cabinet box body; the electronic components are fixed on the installation frames; the main bus is arranged at the upper portion inside the switch cabinet box body; and the main bus and the electronic components are connected by small copper bars. The beneficial effects of the switch cabinet are as follows: the traditional multi-strand twisted wires are replaced by the small copper bars as connecting lines; phenomena of damaging, short circuit and circuit opening can not be generated easily; and the reliability and security of the current transmission are improved. Moreover, the provided switch cabinet has the advantages of simple structure, convenient maintenance, and low production cost and the like.
Description
Technical field
The utility model belongs to electric power system power transmission and distribution technical field, especially relates to a kind of switch cubicle that has little copper bar connecting line.
Background technology
In existing technology, the above main bus bar of 250A is connected with electronic devices and components by rope-lay strand in the low-tension switch cabinet, there is certain slit between each strand twisted wire and the adjacent twisted wire in the rope-lay strand, just have certain resistance, the long-time use can produce a large amount of heats, causes current delivery to be affected, and has great potential safety hazard, and the making more complicated of rope-lay strand, cost is than higher.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, security reliability is high, the switch cubicle that has little copper bar connecting line of low production cost.
The technical solution of the utility model is: the switch cubicle that has little copper bar connecting line, comprise switch cubicle casing, installing frame, electronic devices and components and main bus bar, the switch cubicle box house is provided with installing frame, electronic devices and components are fixed on the installing frame, main bus bar is arranged on switch cubicle box house top, is connected by little copper bar between main bus bar and the electronic devices and components.
Further, described electronic devices and components are circuit breaker or contactor.
Further, between described little copper bar and the main bus bar, all fix by bolt between little copper bar and the electronic devices and components.
Advantage and the good effect that the utlity model has are: the utility model has replaced traditional rope-lay strand as connecting line, adopt little copper bar as connecting line, it is not fragile, be difficult for producing short circuit and opening circuit, reliability and the fail safe of current delivery have been improved, have simple in structure, easy to maintenance, advantage such as production cost is low.
