Abstract
The utility model relates to a low-voltage withdrawable switchgear, which comprises a switchgear body, wherein a drawer-type functional unit chamber is arranged at the front part of the left half side of the switchgear body, and a cable chamber is arranged at the front part of the right side of the switchgear body; a busbar chamber is positioned at the back parts of the drawer-type functional unit chamber and the cable chamber, and metal boards are used for separating the drawer-type functional unit chamber and the busbar chamber from the cable chamber. The utility model has the advantages that: firstly, the drawer-type functional unit chamber, the busbar chamber and the cable chamber are separately and independently designed so as to effectively stop the extension of arc and ensure the whole safety of the switchgear body, and secondly, the structure is compact, the operation is simple and the maintenance is convenient.
Description
Technical field
The utility model relates to a kind of low pressure draw out switchgear cabinet, be mainly used in electric energy conversion, distribution and the control of distribution system power, distribution and the motor control center of industries such as power plant, stone Shan, chemical industry, metallurgy, weaving, skyscraper, belong to power equipment and make the field.
Background technology
Existing low pressure draw out switchgear cabinet, dividing with arrangement of cabinet functional unit is unreasonable, not only maintenance difficulty, and lack enough safety guarantee and safety measure, the safe operation of equipment and maintenance fast both be unfavorable for, also can't realize the quick assembling and the debugging of equipment, and shortage or operability.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of both convenient assembling fast, be convenient to the low pressure draw out switchgear cabinet that connects up and overhaul again.
Design: in order to realize above-mentioned purpose of design.1, the front portion of cabinet is that drawer type functional unit chamber and cable vault, rear portion are the design of adopting metal partion (metp) to isolate between bus-bar room and each chamber, is one of feature of the utility model design.The purpose of doing like this is: the purpose that has both realized dividing according to function cabinet, the independence and the fail safe of each chamber have been increased, can stop the extension of electric arc effectively again, thereby issuable fault is limited in the very little scope, guarantee the overall security of cabinet.2, the design in the drawer type functional unit chamber, be the utility model design feature two.The purpose of doing like this is: because each drawer is a separate functional unit and interchangeable, it can realize pegging graft with turnover line cable in the cable vault, has realized modularization centralized control.3, the design of 32 pairs of auxiliary contacts of drawer back shroud and operating grip, be the utility model design feature three.The purpose of doing like this is: both satisfied the automation user and with the needs of computer interface, the function that makes operating grip have mechanical interlocking and electrical interlock has again increased the fail safe of operation.4, the main bus bar in the bus-bar room adopts the design that the sales counter flat placed type is arranged, be the utility model design feature four.The purpose of doing like this is: both strengthened the ability of the anti-electric power of bus, made the main circuit of device possess carrying short circuit current strength capabilities again.5, the up and down design of outlet passage is arranged in the cable vault, be the utility model design feature five.The purpose of doing like this is: solved the problem that old-fashioned switch cubicle can't be gone up outlet, used convenient.
Technical scheme: low pressure draw out switchgear cabinet, it comprises cabinet, half of front portion, the left side of cabinet is drawer type functional unit chamber, the right half of anterior cable vault that is, bus-bar room adopts metallic plate to isolate between drawer type functional unit chamber and rear portion, cable vault and drawer type functional unit chamber, bus-bar room and cable vault.
The utility model is compared with background technology, and the one, drawer type functional unit chamber, cable vault, bus-bar room stop the extension of electric arc effectively for isolating the design of independence, have guaranteed the general safety of cabinet; The 2nd, compact conformation, easy and simple to handle, easy access.
