LUGAO KYN28 Armored Removable AC Metal Enclosed Switchgear  Features

The framework of handcart is made of steel sheet through the procession of CNC machine tool and rivet welding.   According to the application, the handcarts can be divided into circuit breaker hand-cart, voltage transformer handcart, isolating handcart and metering handcart, etc.   The handcarts of the same specification can be exchanged conveniently.   In the cabinet, the handcart has isolating position, testing position and operating position, each of which is designed with a location device to assure that the handcart can 't move easily at the above-mentioned positions, while the interlock must be unlocked to move the handcart.

The bus is led from one switch cabinet to another one and fixed with static contact box through branch bus.   The fat branch bus is connected through the bolt to the static contact box and main bus,not needing any other line clamps or insulators.   When there is special demand of the clients or the project, the connecting bolt on the bus bar can be encapsulated with insulation and end cap. When the bus crosses the baffle of the switch cabinet, fix it with bus bushing, so that, if there is any internal fault arc, it can prevent the fault spreading to another cabinet and can guarantee the mechanical strength of the bus.

Inside the cable chamber, the current transformer, grounding switch, arrester and cable can be installed, and on the bottom is designed slotted removable aluminum sheet to assure the convenient site construction.

Relay instrument chamber is used to install all kinds of components, such as relays, instruments, signal indicator and operating switch, etc.  In addition, it's available to add a small bus chamber on the top of the instrument chamber according to the demand of the clients, and set 16 lines to control the small bus.

On the handcart chamber, bus chamber and cable chamber is installed pressure releasing device.  When there is internal fault arc in the breaker, main bus or inside the cable chamber, and with the appearance of electric arc, the internal pressure in the switch cabinet rises.  After it rises to a certain pressure, the pressure releasing metal sheet of the top device will be opened automatically, and the pressure and the gas are released to guarantee the safety of the operator and the switch cabinet.

Latching device is used to connect the central exit and cabinet body, and the lifting device is also designed to make it more convenient to open the central exit.  When the central exit stays closed, the connecting strength with the cabinet body is the best and the capability against the internal arcing fault effectively is strengthened.
