A locking system for an enclosure, including a control bracket mounted to a door of the enclosure and configured to slide in a longitudinal direction along a guide rod running through a pin bracket of the control bracket. The control bracket further includes a latching pin to secure the door of the enclosure. A handle mechanism has a push rod that causes the control bracket to slide along the longitudinal direction, also causing the latching pin to move into a position that secures the door.

A switchgear according to the present invention includes a disconnecting unit that includes multiple switches to switch electrical paths by rotation of blades, and a switch housing having a view port, and including the switches arranged therein, wherein planes of rotation of the blades and an arrangement direction of the switches intersect, and the switches are arranged rearward from the view port.

Examples disclosed herein illustrate various implementations of access ports that are to be mounted to various types of electrical enclosures. In some implementations, the access ports are circular to provide ease of installation and to reduce the overall footprint of the access ports.

Lamp for the installation in an electric cabinet comprising at least one electric light source, and an optical device with at least two optical portions for transmitting and redirecting light emitted from said electric light source, wherein the redirection characteristics of one of the optical portions differs from the redirection characteristics of the other optical portion, and wherein the two optical portions are discrete from each other and integrally formed or connected.

In order to reduce service procedure time and labor costs, while increasing overall uptime, the electrical equipment cabinet of the invention includes a main service door that is integrated with the dead front. The dead front panel is fixed to and movable with the main service door, and therefore access to high voltage equipment situated behind the dead front is achieved by simply opening the main service door, without the need to first unlock and open the main service door and then unlock, open, and/or remove the dead front panel. Controls on the front side of the dead front are easily and safely accessible, when the main service door is closed, through a dead front control access door positioned within an opening of the main service door.

A handle for a compartment of a low, medium or high voltage switchgear includes: a body part; a hand grasping part; and a lock. The handle is movable from a closed position to an open position. When the handle is in the closed position, the handle is not useable to open a door of a compartment of the switchgear. When the handle is in the open position, the handle is useable to open the door of the compartment of the switchgear. In the open position, the hand grasping part is positioned so as to be graspable by a human user. In the closed position, a transition of an active element in the compartment of the switchgear from a quiescent state to an active or potentially active state activates the lock. Activation of the lock stops the handle from moving from the closed position to the open position.

A container energy storage system is provided, including a container, a plurality of functional assemblies, and a splitting plate, wherein the splitting plate has a connecting port electrically connected to the functional assemblies. The container includes a hollow main body having an opening and two doors pivotally connected to the hollow main body. The functional assemblies are disposed in the hollow main body, and the splitting plate is disposed between the functional assemblies and the opening. When the doors are in a closed position, the doors cover the opening.

The present invention relates to a module replacement device of a high voltage direct current transmission system. In the present invention, a replacement base (40) is provided in a structure (1) by using a support member (70) such that a sub-module (30) movably provided at a fixing base (10) of the structure (1) can be replaced by being withdrawn outside of the structure (1). A rear end of a base plate (42) of the replacement base (40) is hooked to an insulation support part (9) of the structure (1), and a front end of the replacement base (40) is supported by the support member (70) hooked to one side of the structure (1). The support member (70) is provided with a turn buckle (74) so as to adjust the replacement base (40) such that the replacement base is horizontally provided thereto. The rear end of the replacement base (40) is provided with a rail connection guide (62) for matching a fixing rail (16) of the fixing base (10) provided in the structure (1) with a guide rail (51) of the replacement base (40). The rail connection guide (62) has a rail slot (64) so as to guide the fixing rail (16) to the guide rail (51) side. According to the present invention as above, the replacement base (40) can easily and firmly be provided in the structure (1) such that the module (30) can be replaced in an easy and safe manner.

A power cabinet, which includes a cabinet body and an electric reactor, a power unit and a switch arranged in the interior of the cabinet body. In the interior of the cabinet body of the power cabinet, the electric reactor is arranged close to a first side in the interior of the cabinet body, and the power unit and the switch are arranged on a second side in the interior of the cabinet body, opposite to the first side. Moreover, these electric reactor, the power unit and the switch are all located in a lower space. In addition, in the power cabinet, the electric reactor and power unit dissipate heat in different chambers from the switch dissipates heat.

A motor control center (MCC) unit includes a drawer having a space for accommodating a circuit breaker, a hinge bracket installed on one of left and right sides of the drawer, a base connected to the hinge bracket by a hinge shaft, and a display mechanism installation plate fastened to the base by a fastening member. Although a display mechanism or a display mechanism installation plates are different according to sizes or models of the MCC unit, a base and a hinge bracket may be commonly used.
