Abstract
The invention discloses a steel-clad movable-type alternating current metal-closed switchgear and relates to the technical field of electrical control switchgears. A breaker handcart is arranged at the upper end of the right side in a switch cabinet, a heater is arranged in the breaker handcart, a secondary socket and an interlocking rotating device are connected to the upper end of the breaker handcart, and the inner side of the breaker handcart is connected with a first fixed contact and a second fixed contact. The first fixed contact is connected with a main bus plate, the second fixed contact is connected to a current transformer of the left side of the switch cabinet, a grounding switch device is arranged at the lower end of the left side of the switch cabinet, and a lightning arrester is connected to the lower end of the grounding switch device. The steel-clad movable-type alternating current metal-closed switchgear is mainly applied to power transmission of power plant small motors and power receiving of secondary substations of industry and mining enterprises and power systems and has the linkage functions of preventing on-load lifting of the breaker handcart and preventing error switching-on of a grounding switch in an electrified mode.
Description
Technical field
The present invention relates to electric controling switch equipment technical field, be specifically related to armoured removable type alternating.
Background technology
Switch cubicle (switch cabinet) is a kind of electric equipment, and switch cubicle outside line is introduced into master switch in cabinet, then enters sub-control switch, and each shunt needs to arrange by it.As instrument, automatic control, motor magnetic switch, various A.C. contactors etc., what have also establishes hyperbaric chamber and low-pressure chamber switch cubicle, is provided with high voltage bus, as power plant etc., the low-frequency load reduction be also provided with as protecting capital equipment had.The Main Function of switch cubicle (switchgear) carries out generating electricity in electric power system, transmits electricity, in the process of distribution and electric energy conversion, carries out folding, control and protection power consumption equipment.Parts in switch cubicle mainly contain the compositions such as circuit breaker, isolating switch, on-load switch, operating mechanism, instrument transformer and various protective devices.The sorting technique of switch cubicle is a lot, as being divided into withdraw-type switch cabinet and fixed switching cabinet by circuit breaker mounting means; Or according to the difference of cabinet body structure, open type switch cubicle, metal closed switch cabinet and metal enclosed armoured switch cabinet can be divided into; High-tension switch cabinet can be divided into again, Medium Voltage Switchgear and low-tension switch cabinet etc. according to electric pressure difference.Mainly be applicable to various different occasion such as power plant, transformer station, petrochemical industry, metallurgical steel rolling, industry light industry textile industry, industrial enterprise and residential quarters, skyscraper etc.
But existing switch cubicle uses and relatively limits to, and is all generally pointed, can not uses most electrical control situation.
Summary of the invention
