The utility model has reasonable structure, high safety and reliability, fully enclosed, insensitive to outside conditions, etc, which is a power distribution device with excellent performances, miniaturization, and maintenance free.
Description
Affiliated field
The utility model relates to a kind of equipment of accepting and distributing electric energy, and the fixed miniaturization metal closed switch cabinet of particularly a kind of intellectuality is applicable in 3～10KV three-phase alternating current 50HZ system.
Background technology
The big electric current of people's use now, the switch cubicle of high breaking, cabinet overall dimension is bigger, installs and uses to take up room greatly, because the volume of switch cubicle is bigger, has increased cost greatly, other five anti-functions are all perfect inadequately, complex structure, operation easier is big, and coefficient of safety is not high.Existing in addition switch cubicle is creepage littler than distance, the edge that does not reach national DL404 (indoor ac high-voltage switch cubicle order technical conditions) requirement must not be less than the requirement of 20mm/kv in the face of the creepage ratio distance in ground, there are not five anti-functions, and, degree of protection is on the low side, in the comparatively abominable occasion of environment for use, is easy to take place flashover, puncture when big as humidity, thereby pernicious power outage takes place, have a strong impact on people's lives and industrial production.
Summary of the invention
Purpose of the present invention promptly is to overcome the shortcoming of prior art, and a kind of compact conformation, strong, the safe intelligent fixed miniaturization metal closed switch cabinet of resistance to corrosion are provided, and its mechanical strength is good, precision height, simple to operate, five anti-interlockings reliably.
The purpose of this utility model is achieved through the following technical solutions: the fixed miniaturization metal closed switch cabinet of a kind of intellectuality, comprise cabinet, the cabinet internal upper part is provided with insulator, be installed on the insulator supporting bracket, a busbar is installed on the insulator, the upper back is connected with isolating switch with a busbar output in cabinet, rear lower is connected with isolating switch down with a busbar output in cabinet, there are integrated indoor high-voltage vacuum circuit breaker and axle and two pull bars in preceding middle and lower part in cabinet, be fixed on the cabinet right plate by jockey, current transformer is installed on vertical clapboard, following isolating switch is positioned at the vertical clapboard bottom, also be provided with insulator on the supporting bracket, last insulator is connected with last isolating switch output and integrated indoor high-voltage vacuum circuit breaker input by a busbar, integrated indoor high-voltage vacuum circuit breaker concrete structure is seen the integrated indoor high-voltage vacuum circuit breaker of Chinese patent (patent No. ZL96232296.2), be provided with insulator down in the rear board bottom of cabinet, link to each other with following isolating switch by a busbar, the output of current transformer connects down the isolating switch input by a busbar, link to each other with lightning arrester by a busbar, lightning arrester is installed on the cabinet lower shoe again.
Last isolating switch, following isolating switch are the miniaturization switch, these two groups of isolating switches rotated conductors ground connection when the disjunction position.
By top narration as can be seen, the utlity model has following advantage: rational in infrastructure, small and exquisite, the cabinet size is 2/3rds of an existing product; , safe in utilization, reliable, operating mechanism and five anti-mechanisms are integrated, realize simple to operately, and five prevent that performances are safe and reliable; Totally-enclosed, be not subjected to the influence of factors such as external environment, be the non-maintaining power distribution equipment of a kind of superior performance miniaturization.
