產(chǎn)品概述 Product general

DZ15LD是我公司生產(chǎn)的一款多功能自動(dòng)保護(hù)開關(guān)，集斷相、漏電保護(hù)為一體。即可對運(yùn)行在交流380V、50Hz的線路中對電動(dòng)機(jī)進(jìn)行多方面的自動(dòng)保護(hù)，又可以作為不頻繁啟動(dòng)電動(dòng)機(jī)的開關(guān)，并且對配電變壓器的跌落開關(guān)掉閘或總保險(xiǎn)絲熔斷而引起的多合電動(dòng)機(jī)缺相運(yùn)行導(dǎo)致變壓器過流損壞的事故能起到一定預(yù)防作用。

此保護(hù)開關(guān)的優(yōu)點(diǎn)是解決了市場上多種開關(guān)高壓斷相(跌落開關(guān)掉閘)不起作用的難題。無論是高壓跌開掉閘，低壓保險(xiǎn)絲燒壞，電機(jī)三相繞組一相不通電造成單相運(yùn)行，都能可靠的起到保護(hù)作用。

DZ15LD is a multifunctional automatic protection switch produced by our company, which integrates phase interruption andleakage protection. lt can automatically protect motors in 380V and 50Hz AC lines in many aspects,and can alse be used as aswitch for starting motors infrequenty. lt can also play a certain role in preventing transformer over-current damage accidents

caused by multiple motors running without phase due to drop switch of distribution transformer or fuse blowing.The advantage of this protection switch is that it solves the problem that many kinds of switches in the market do not work dueto high voltage phase failure(drop switch tripping). No matter if the high voltage fas,the brake falls of, the low votage fuse blowsout, and one phase of the three-phase winding of the motor is not energized, resulting in sinale-phase operation. it can reliablyplay a protective role.
