“知識大講堂”又和大家見面啦!

本期內(nèi)容仍然圍繞我們的“高低壓配電產(chǎn)品”系列,著重分析講解我司生產(chǎn)的“XDD計量箱”?!癤DD計量箱”廣泛用于樓宇、廣場、車站及工礦企業(yè)等各種場所,便于監(jiān)測、計量電能使用情況。作為配電系統(tǒng)的終端設備,“XDD計量箱”適用于民用或者在非專業(yè)人員可以進入的場合使用。那么它的產(chǎn)品特性是什么,又有什么樣的電氣特點?今天就讓我們來了解一下它吧...

XDD計量箱

一. 產(chǎn)品簡介

I. Brief introduction :

XDD系列計量設計依據(jù)標準GB7251.3-2006 《低壓成套開關設備和控制設備》等國家標準及歐洲標準EN61493-1、2。是配電控制系統(tǒng)中計量用的主要電氣產(chǎn)品。廣泛用于各種樓宇、廣場、車站及工礦企業(yè)等場所。作為配電系統(tǒng)的終端設備。這類設備適合用于民用或適合在非專業(yè)人員可以進入的場合使用。用于監(jiān)測、計量電能使用情況。

XDD series metering design is based on the standard GB7251.3-2006 “l(fā)ow voltage switchgear and control equipment” and other national standards and European standard EN61493-1, 2. It is the main electrical product in the power distribution control system and is widely used in various buildings, squares, stations and industrial and mining enterprises and other places as the power distribution system terminal equipment. This type of equipment is suitable for civilian use or the occasions where non professional personnel have access to. It is used for monitoring and measurement of electric energy.

二. 主要性能與特點

II. Main performance and features :

1. 本產(chǎn)品用于交流、額定頻率50Hz、額定電壓380/220V,額定電流不超過200A的電氣計量系統(tǒng)。

2. 箱體外殼可以采用碳鋼噴涂、不銹鋼、聚碳酸酯制作,防護等級IP30。

3. 電能計量箱按用途分為室內(nèi)和室外兩種;按電流分為直遷和套互感器;按電壓分為低壓和高壓;按使用環(huán)境分為防水型和普通型。

4. 電能計量箱主要結構形式為分體式結構。分體式結構分為上箱體和下箱體,上箱體和下箱體通過聯(lián)接件連接在一起,上箱體和下箱體可以組合或拆裝使用;上箱體裝上設有可視窗口,可視窗口安裝透明罩,電表安裝在上箱體中,通過

透明罩可以看見電表指示;下箱體中設有可安裝漏電、空氣開關等器件的安裝孔和接線柱,上箱體電表可通過導線或銅帶或接線柱與下箱體中的有關的器件連接;箱體的側面開通孔,使多個電能計量箱可以組合安裝使用。本實用新型電表箱具有安裝方便、走線隱蔽、可任意組合、拆裝使用等優(yōu)點。

5. 可根據(jù)用戶需要配制不同廠家的斷路器、三相電能表、單相電能表等。

6. 安裝方式靈活:明裝掛墻式、暗裝掛墻式。

1. This product is used for the electrical measurement system of AC, rated frequency 50Hz, rated voltage 380/220V and rated current not exceeding 200A.

2. The box shell can be made of carbon steel spraying, stainless steel and polycarbonate production, protection grade IP30.

3. By the usage, the electric energy metering box is divided into indoor type and outdoor type; according to the current is divided into direct and sets of transformers; according to the voltage divided into low pressure and high pressure; according to the environment is divided into waterproof type and ordinary type.

4. The main structure of electric energy metering box is split type structure, which is made of an upper box body and a lower box body. The bodies are connected together through connecting pieces. The upper box body and the lower box body can be used in combination or used independently; The upper box body is provided with a visual window with a transparent cover, meter is installed in the upper box, through the transparent cover can see electric meter indication; The lower box body is provided with mounting hole and wiring terminal for electric leakage and air switch. The upper box meter and lower box devices can be connected together by wire or copper tape or wiring column; Opening holes on the sides of the box body make several electric energy metering boxs can be assembled using. The utility model has the advantages of convenient installation, line hidden, and can be assembled and used in any combination.

5. According to the user need, different manufacturers of circuit breakers, three-phase electric energy meter, single-phase electric energy meter, etc. can be provided.
6. The installation method is flexible: wall mounted type or concealed hanging wall type.
