鎧裝移開式交流金屬封閉開關設備結構簡介 Structure Introduction

開關設備按GB3906-91 中的鎧裝式金屬封閉開關設備而設計。整流器體是由柜體和中置式可抽出部件（既手車）兩大部分組成，見圖

1。柜體分四個單獨的隔室，外殼防護等級為IP4X，各小室間和斷路器室門打開時防護等級為IP2X。具有架空進出線、電纜進出線及其它功能方案，經(jīng)排列、組合后能成為各種方案形式的配電裝置。本開關設備可以從正面進行安裝調試和維護，因此它可以背靠背組成雙重排列和靠墻安裝，提高開關設備的安全性、靈活性，減少了占地面積。

The switch equipment is designed according to GB3906-91 metal armoring 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 divides into four separate rooms, the outer covering protection grade is IP4X,when each small room and the circuit breaker is opened, the protection grade is IP2X.It can suspend the inlet, outlet line, cable’s inlet, outlet line and other function plan. After 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 手車Handcar

手車骨架系采用薄鋼板經(jīng)CNC 機床加工后經(jīng)鉚、焊而成的。根據(jù)用途，手車可分為斷路器手車、電壓互感器手車、隔離手車、計量

手車等等，相同規(guī)格的手車能方便互換。手車在柜內有隔離位置、試驗位置和工作位置，每一位置均設有定位裝置，以保證手車處于以上

位置時不能隨便移動、而移動手車時必需要解除聯(lián)鎖。

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.

B 母線室Bus chamber

母線從一個開關柜引至另一開關柜，通過分支母線和靜觸頭盒固定。扁平的分支母線通過螺栓連接于靜觸頭盒和主母線，不需要任何其它的線夾或絕緣子聯(lián)接。當用戶和工程特殊需要時，母線排上的聯(lián)接螺栓可用絕緣和端帽封裝。在母線穿越開關柜隔板時，用母線套管固定。如果出現(xiàn)內部故障電弧，能限制事故蔓延到鄰柜，并能保障母線的機械強度。

The bus is led from one switch cabinet to another one and fixed with static contact box through branch bus. The flat 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 me-chanical strength of the bus.

C 電纜室Cable chamber

電纜室內可安裝電流互感器、接地開關、避雷器以及電纜、并在其底部配制開縫的可卸鋁板，以確?，F(xiàn)場的施工方便。

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 siteconstruction.

D 繼電器儀表室Relay instrument chamber

繼電器儀表室用于安裝各類繼電器、儀表、信號指示、操作開關等元器件。此外可根據(jù)用戶要求在儀表室頂部增加小母線室，可敷設

十六路控制小母線。

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.

泄壓裝置Pressure releasing device

在手車室、母線室、電纜室的上方設有泄壓裝置，當斷路器或主母線、電纜室內發(fā)生內部故障電弧時，伴隨電弧的出現(xiàn)，開關柜內部氣壓上升，達到一定的壓力后，頂部裝置的壓力釋放金屬板將被自動打開，釋放壓力和排泄氣體，以確保操作人員和開關柜安全。

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.

鎖扣結構Latching device

中門與柜體之間的聯(lián)接采用鎖扣結構，并配以提升機構，使中門開啟更為方便，當中門處于關閉狀態(tài)時，其與柜體的聯(lián)接強度更好，增強了有效抗擊內部燃弧故障的能力。

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.
