一、概述

KLYBDC2系列隔爆型單相異步電動(dòng)機(jī)是我公司KLYBDC系列更新?lián)Q代的防爆電機(jī)基本系列，本系列電動(dòng)機(jī)具有體積小、重量輕、外型美觀、安全可靠的運(yùn)行、壽命長(zhǎng)，性能優(yōu)良，安裝使用與保養(yǎng)維修方便。

本系列電動(dòng)機(jī)的功率等級(jí)、安裝尺寸符合國(guó)際電工委員會(huì)（1EC）標(biāo)準(zhǔn)，其對(duì)應(yīng)關(guān)系與德國(guó)DIN42673標(biāo)準(zhǔn)相同，有利于出口設(shè)備的備品備件。

本系列電動(dòng)機(jī)防爆性能符合GB3836.1--2000《爆炸性氣體環(huán)境用電氣設(shè)備第1部分》和GB3836.2--2000《爆炸性氣體環(huán)境用電氣設(shè)備第2部分：隔爆型“d”》的規(guī)定，也符合IEC91-1，BS4683和EN50018的規(guī)定，制成隔爆型。防爆標(biāo)志為ExdⅡ AT4、ExdⅡ BT4，適用于有爆炸性氣體混合物存在的場(chǎng)所。

ExdⅠ適用于甲烷或煤塵的爆炸性混合物存在的煤礦井下非采掘工作面環(huán)境。

ExdⅡ AT4適用于工廠用Ⅱ類A級(jí)，溫度組別為T(mén)1、T2、T3和T4組爆炸性氣體混合物存在的環(huán)境。

ExdⅡ BT4適用于工廠用Ⅱ類B級(jí)，溫度組別為T(mén)1、T2、T3和T4組爆炸性氣體混合物存在的環(huán)境。

在KLYBDC基本系列電動(dòng)機(jī)基礎(chǔ)上，也可制成KLYBDC2-W戶外型、KLYBDC2-WF1戶外中等防腐型等氣候環(huán)境條件。

1、General Description

      Superseding the old generation of series KLYBDC2,series KLYBDC series flameproof single phass asynchronous motors,the basic series of flameproof motors,are developed and manufactured by our company.This series motors are of remarkable features,such ascompact construction,light weight,attractive appearance,safe and reliable operaton life,excellent performance and easy maintenance.

      For this series motors,the output ratings and mounting dimensions conform to the specifications of IEC standards and the correlation between them basically agrees with EIN42673.The motors are easy to complete with export machinery and equiment and to supply as spare accessories in the improt equipment.

     This series motors are designed and manufactured into flameproof type and the flameproof property conforms to China National Standards.

     GB3836.1--2000 Electrical Apparatus for Explosive Gas Atmospheres General Requirements

     GB3836.2--2000 Electrical Apparatus for Explosive Gas Atmospheres Flameproof Enclosure“d”and stabdards

IEC79-1,BS4683 and EN50018,The explosion protection marks are ExdⅡ AT4,ExdⅡ BT4.They are safe to use in the locations where there are explosive mixtures of gas-and vapor-air.

     “ExdⅠ”-safe for use in the non-mining surfaces of underground coal mines where the explosive minxtures

Of methane or coal-dust are present.

     “ExdⅡ AT4”safe for use in plants where the explosive mixtures of Ⅱ A Class,T1,T2,T3 orT4 are present.

     “ExdⅡ BT4”safe for use in plants where the explosive mixtures of Ⅱ B Class,T1,T2,T3 orT4 are present.

     based on series YB2 motore,the motors can also be manufactured for special environments,such as outdoor locations(KLYBDC-WF1 type.）
