Overview

This equipment is indoor metal armouring with drawable switchgear (hereafter referred to as switchgear. 3.6-12kilovolt three phases AC 50Hz single bus bar and the single bus bar subsection system's complete electricity distribution equipment is used in the power plant, small and medium-sized generator power transmission, industry and mining business power distribution as well as electrical industry system's second transformer substation's electric take-over, power transmission and large-scale high-pressure motor starting and so on.

The purpose is to control, protect and monitor. This switch equipment is up to the standard of IEC298,GB3906. It can prevent the charge from pushing and pulling the breaker, from opening and closing the breaker, from insulation with electricity by mistake, from an earthed switch closing the breaker, and from opening the switch's interlock when it is with electricity mistakenly.

It can be done not only with the VSI vacuum circuit breaker but also with ABB Corporation's VD4 vacuum circuit breaker. It is indeed a kind of power distribution equipment with superior performance.

The Main Technical Parameters

Structure Introduction

The switch equipment is designed according to GB3906-91 metal armouring seal switch equipment. The rectifier body is made up of the cabinet body and draw-out parts (namely handcart) placed in the middle. See Charter 1.

The cabinet is divided into four separate rooms, the outer covering protection grade is IP4X, and when each small room and the circuit breaker are opened, the protection grade is IP2X.

It can suspend the inlet, outlet line, cable's inlet, outlet line and other function plan. After being arranged and combined, it can become each kind of plan form of the power distribution equipment.

This switch equipment may be installed and maintained from the frontage, therefore it may compose the dual arrangement back to back and be installed against the wall, improving the switch equipment's security and flexibility and making full use of the occupying area.

A Handcart

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

B Bus chamber

The bus is led from one switch cabinet to another one and fixed with a static contact box through the 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 a special demand from the clients or the project, the connecting bolt on the bus bar can be encapsulated with insulation and an 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 from spreading to another cabinet and can guarantee the mechanical strength of the bus.

C Cable chamber

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

D Relay instrument chamber

The relay instrument chamber is used to install all kinds of components, such as relays, instruments, signal indicators operating switches, etc. In addition, it's possible 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.

E Pressure releasing device

On the handcart chamber, bus chamber and cable chamber are installed pressure-releasing devices. When there is an internal fault arc in the breaker, main bus or inside the cable chamber, and with the appearance of an 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 will be released to guarantee the safety of the operator and the switch cabinet.

F Latching device

The 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.
