Description

Multifunctional composite switchboard {all competent composition electric panel}

The present invention relates to a multifunctional composite water switchgear, which minimizes the system installation space and diversifies the function of the water switchgear, which is installed when the electric power is installed in a place such as a building or a factory.

In particular, the present invention is to minimize the area occupied by the substation room by developing a closed switchgear of 22,900 volts in a multi-functional complex, reducing the cost of securing the installation space, which is the biggest problem of the customer to install their own electrical equipment In addition, it is easy to install and troubleshoot, and the safety manager can conveniently monitor and control the system for safe operation.

If there is a large amount of power used, such as buildings and factories, establish complementary liability thresholds with the utility company, and elect electric security officers by providing electric equipment after the responsibility thresholds with the customer's own electrical equipment with the number of switchboards. As a substitute, the company is responsible for supplementary responsibilities, and the electric and electrical equipment such as switchboards and power distribution panels not only change the power distribution method and the configuration of the main circuit depending on the purpose, type of business, size, location, importance of buildings, factories, etc. Capacities range from hundreds of kilowatts to tens of thousands of kilowatts, which made it difficult to think of standard equipment suitable for all occasions.

Therefore, the switchgear, which is a private electric installation, has to be satisfied. Suitable for building or factory facilities; It should be made of simple equipment that does not reduce the reliability of the equipment and does not cause inconvenience in operation or maintenance; There is no risk of fire due to electrical installations and there should be safe installations without electric shocks; The instrument's performance must be excellent, reliable, and have a long service life; Minimize the installation cost by using small and light equipment, and sixth; The arrangement of the equipment should be reasonable, and the operation, maintenance and breakdown measures should be free from erroneous operation.
