Abstract
The utility model provides an assembly split rigid switch cabinet body, which comprises an upper cabinet body and a lower cabinet body. An upper isolation cutter installation supporting part is fixed into the upper cabinet body; and a lower isolation cutter installation supporting part and a circuit breaker installation supporting part are fixed into the lower cabinet body, wherein the upper cabinet body is fixedly arranged on the lower cabinet body. Besides, the proportion of the height of the upper cabinet body to the height of the lower cabinet body is 1:2. As the switch cabinet body is split and formed by assembling the upper cabinet body and the lower cabinet body and the proportion of the height of the upper cabinet body to the height of the lower cabinet body is 1:2, the design simplifies process and facilitates assembly. Moreover, as the height of the upper cabinet body is smaller, the upper cabinet body can be processed by adopting leftover materials so as to improve material use ratio. By adopting split technique, the switch cabinet body can be integrally finished by assembling after each portion is independently finished, so that assembly precision of the cabinet body is improved, installation and maintenance are convenient, and efficiency is increased. In addition, as the cabinet body is formed by assembling the upper cabinet body and the lower cabinet body, the integral rigidity of the cabinet body is enhanced.

In order to solve the problems of the technologies described above, the split type hard-switch cabinet of a kind of assembling of the utility model cabinet comprises cabinet, and the cabinet internal fixation is provided with isolation knife a part and a circuit breaker installation part are installed; Wherein, described cabinet comprises cabinet, lower cabinet body, and the described cabinet of going up is fixedly installed on the described lower cabinet body, and the height of described upward cabinet is 1: 2 with the ratio of lower cabinet body height.
The split type hard-switch cabinet of above-mentioned a kind of assembling cabinet, wherein, described isolation knife is installed part one side and is provided with stiffener, strengthens a part; Described stiffener is fixedlyed connected with cabinet, and described reinforcement props up that a part is installed with described isolation knife respectively in the part both sides and described stiffener is fixedlyed connected.
The split type hard-switch cabinet of above-mentioned a kind of assembling cabinet, wherein, it is the G type member that two ends are provided with shut that part is propped up in described reinforcement.
The split type hard-switch cabinet of above-mentioned a kind of assembling cabinet, wherein, described isolation knife is installed by a part and a described circuit breaker installation part is a few font members.
The utility model can be realized following beneficial effect:
1, because the utility model is split type cabinet, assembled by upper and lower two parts cabinet, upper and lower cabinet height ratio is 1: 2, this design simplification technology, easy to assembly, and because Over-The-Counter height degree is less, can adopt leftover pieces processing, improve stock utilization; Adopt to divide a body technique, can independently finish each one after, overall package is finished again, has improved the cabinet assembly precision, and convenient for installation and maintenance, has improved the efficient height; In addition, cabinet is assembled by upper and lower cabinet, has improved the integral rigidity of cabinet.
2, because described isolation knife installation part one side is provided with stiffener, strengthens a part, improve the cabinet local stiffness, guarantee that the isolation knife combined floodgate puts in place, has guaranteed the installation of cabinet.
3,, thereby improve the local stiffness of cabinet because described isolation knife is installed a part and a described circuit breaker installation part is a few font members, and during installation, the base that a part is installed by isolation knife connects, and is easy for installation, and owing to a few font member non-deformabilities are good.
