Abstract
The utility model discloses a kind of central switch equipment, belong to switchgear technical field.It is metal enclosed sheathed structure, be made up of cabinet and mid-extraction parts (handcart) two large divisions, it is characterized in that: described cabinet is divided into four independently compartments, handcart compartment, busbar compartment, cable compartment and relay compartment respectively, containing current transformer, earthed switch, cable, lightning rod and earthing main bus in described cable compartment, described handcart compartment is provided with the observation window of visiting of rectangle.Its advantage is: this switchgear is metal enclosed sheathed structure, this equipment has built on stilts line, cable incoming-outgoing wire and other function scheme, the complete distribution system of various scheme can be formed side by side, this equipment can carry out installation and maintenance from front, therefore can form dual arrangement back-to-back or install by wall, improve the fail safe of switchgear, flexibility, decrease floor space, safe and reliable, saving space, repair and maintenance is very convenient.
Description
Technical field
The utility model relates to switchgear technical field, is specially a kind of central switch equipment.
Background technology
The indoor complete power distribution equipment of central switch equipment system 3 ~ 10 kilovolts of three-phase alternating current 50HZ single busbar connections and sectionalized single busbar connection system; be mainly used in power plant, medium and small generator power transmission, industrial and mining enterprises, powered, the power transmission of skyscraper distribution and power system substation and Large-scale High-Pressure engine start etc., and circuit is carried out control, protection and detecting.
A lot of statistics shows, the ratio that switch cubicle mechanical breakdown occurs is the highest, this is because the element be associated with mechanically actuated operation is very many, comprise splitting or integrating lock circuit in series and have a lot of link, and the operation of switch is random, sometimes also inoperation once, sometimes but wants continuous action for a long time.
Switchgear will ensure the connectedness that electric loop is good, the performance of the elements such as splitting or integrating brake cable circle, auxiliary switch is all guaranteed, ensure the reliability of the operating mechanism of switchgear, this not only requires that switchgear intensity wants enough, structure wants reliable, and more switching devices whole line function scheme and debugging maintenance have strict requirement.
Utility model content
The utility model is for the technical problem that solves for providing a kind of central switch equipment, and it is metal enclosed sheathed structure, and this equipment has built on stilts line, cable incoming-outgoing wire and other function scheme, can form the complete distribution system of various scheme side by side.
The utility model technical solution problem adopts following technical scheme:
A kind of central switch equipment is provided, it is metal enclosed sheathed structure, it is made up of cabinet and mid-extraction parts (handcart) two large divisions, it is characterized in that: described cabinet is divided into four independently compartments, handcart compartment, busbar compartment, cable compartment and relay compartment respectively, containing current transformer, earthed switch, cable, lightning rod and earthing main bus in described cable compartment, described handcart compartment is provided with the observation window of visiting of rectangle.
As preferred embodiment, the shell protection grade of described central switch equipment cabinet is IP4X.
As preferred embodiment, described central switch equipment can form dual arrangement back-to-back or install by wall.
As preferred embodiment, described handcart compartment, busbar compartment and cable compartment are equipped with pressure release passage.
As preferred embodiment, described observation window of visiting can to observe in compartment handcart present position and the display of splitting or integrating lock thereof, energy storage situation.
The utility model compared with prior art, its beneficial effect is: this switchgear is metal enclosed sheathed structure, this equipment has built on stilts line, cable incoming-outgoing wire and other function scheme, the complete distribution system of various scheme can be formed side by side, this equipment can carry out installation and maintenance from front, therefore can form dual arrangement back-to-back or install by wall, improve the fail safe of switchgear, flexibility, decrease floor space, safe and reliable, saving space, repair and maintenance is very convenient.
