Functions and Features
The HXGN15-12(Z) switchgear is a metal-enclosed box-type structure. The cabinet frame is welded from angle steel. The cabinet is divided into circuit breaker chamber, busbar chamber, cable chamber and instrument chamber, etc., separated from each other by partitions.
The circuit breaker is located in the lower part of the cabinet body. The rotation of the circuit breaker is connected with the operating mechanism by a pull rod. The upper terminal of the circuit breaker is connected with the upper isolating switch, and the lower terminal of the circuit breaker is connected with the lower isolating switch and the lower outgoing cable connection terminal. A pressure release channel is also provided between the compartments. When internal arc short circuit occurs, gas can release pressure through the exhaust channel. To control equipment and DL/T402, DL/T404 standards, achieving the “five preventions” interlock.
The busbar chamber is located at the upper part of the cabinet body. In order to reduce the cabinet height, the busbars are arranged in product characters, supported by 7350N bending strength ceramic insulators, and the busbar is connected with the upper isolating switch terminal, which is also the compartment between the cabinet and the cabinet.
The cable chamber is located in the lower part of the cabinet body. Voltage display devices can be provided on the supporting insulators in the circuit breaker chamber, and the wires are fixed on the bracket. For the main connection or linking scheme, this chamber is the linking cable chamber. The relay chamber is located in the upper front part of the cabinet body. Various relays can be installed on the mounting plate in the chamber, and supporting brackets are provided in the chamber. Indicators and components such as signal elements can be installed on the door, and a second small busbar can also be laid on the top.
The operating mechanism of the circuit breaker is installed at the left front position, and the operating and interlocking mechanisms of the isolating switch are above it. The switch cabinet is double-sided maintenance. The secondary components in the relay chamber are maintained in front, the mechanism linkage and transmission parts are maintained in front, and the main wires and cable terminals are maintained behind. A lighting lamp is installed in the circuit breaker chamber. A national standard socket is provided below the door, with parallel grounding busbar, specifications: 3×30mm.
Mechanical interlock: in order to prevent live separation and closing of the isolating switch, prevent mis-opening and closing of the circuit breaker, prevent live closing of the grounding switch; prevent live closing of the earth switch; prevent mistakenly entering the live compartment when the earth switch is in the closing position, the switch cabinet has corresponding reliable mechanical interlocks to ensure operational safety. For product dimensions and detailed structure (see Figure 1, Figure 2, and Figure 3).
