| 一、產品概述 Genera |
| XKM/DFY1、2系列電能計量聯(lián)合接線盒是電能計量裝置中的專用試驗接線盒，適用于額定電壓660V，額定電流5~20A 的二次回路中，作為在帶負荷情況下安全調換或現(xiàn)場校驗電能表、電氣指示 儀表、繼電保護等電氣設備之用。確保操作時的人身安全，提高現(xiàn)場工作效率。 二十多年來，本公司依靠電力行業(yè)專家工程師的支持和自己不斷開拓創(chuàng)新的精神，對傳統(tǒng)接線盒進行了較大的改進?，F(xiàn)將其特點簡單介紹如下： 1. 該接線盒的絕緣外殼是采用高級玻璃鋼纖維絕緣材料經熱高溫高壓壓制而成，具有耐高溫、高壓、不易碎裂、防霉變、外形美觀大方等許多優(yōu)點，特別適用于沿海地區(qū)及高溫場所。目前市場上采用的大部分多是塑料和膠木型：塑料型具有不耐高溫的缺點，由于銅導線具 有柔軟的特性，即使導線壓緊后經過一段時間的使用仍會產生松動現(xiàn)象，造成接線盒發(fā)熱而損壞接線盒體。膠木型具有不耐潮濕易吸水霉變漏電、強度差、易碎裂的缺點。 2. 透明盒采用帶防誤接操作功能。其優(yōu)點是：防止供電部們現(xiàn)場校驗人員校驗結束后因疏忽大意而沒有將連接片復位使盒蓋蓋不上去，提醒工作人員檢查復位，從而在硬件設施上給予保障，杜絕因疏忽大意而使計量造成錯計、漏計。 3. 針對某些用電企業(yè)偷電現(xiàn)象時有發(fā)生，我公司特設計了二用全封閉透明罩殼，既可以單獨卸下不用也可以配合使用。起到防止從接線盒處偷竊電可能性發(fā)生的保護。同時透明蓋方便現(xiàn)場檢查人員檢查線路。 4. 本公司現(xiàn)已開發(fā)了整體防竊電防誤操作型三相四線及三相三線接線盒來替代傳統(tǒng)DFY系列接線盒，具有防竊電、防誤操作、易于現(xiàn)場檢測現(xiàn)已全面推廣上市。 |
| XKM/DFY1 and 2 series energy-measuring combined terminal block boxes are special test terminal boxes among the energy-measuring devices, are suitable for secondary circuits of rated voltage of 660V and rated current of 5~20A, used for safety changing with loads or inspecting such electric equipment as watt-hour meter, electric indicating meter and relaying protection device on site, guaranteeing personal safety and improvement of fieldwork efficiency. In the past two decades, our company has made great improvement to traditional terminal block box depending on the expert engineers of electric power industry as well as our pioneering and inn- ovative spirit. Major characteristics of our products as follows: 1. The insulating shell of terminal box is made of top grade glass reinforced plastics insulating mat- erials by means of high-temperature high-pressure pressing, has advantages of high-temperature and high-pressure resistance, not easy to break, mildew resistance, elegant appearance, etc, esp- ecially suitable for coastal areas and high-temperature locations. Most on the market today are of plastic and bakelite type: plastic type has the shortcoming of could not withstand high temperature, the copper conductor would become loose after a period of use even after being firmly pressed due to its flexible characteristic, it would lead to heating of ter-minal box and the box body would be damaged. Bakelite type has shortcomings of poor strength, fragile, mildewing and easily being affected by damp. 2. The transparent box has function of anti wrong-wiring or misoperation, it has advantages of prev- enting failure of resetting the cover, as the connecting sheet has not been reset due to negligence of the field inspector of power supply department after inspection, reminding the worker to check the resetting condition, providing guarantee of hardware facilities, putting an end to wrong metering or leaked metering due to negligence. 3. Aiming at the electricity theft phenomenon in some enterprises, our company designed the two- purpose full-closed transparent shell that can either be removed or remained, preventing from possible theft from the terminal box. Meanwhile, the transparent shell is convenient for inspectors to check the circuitries. 4. Our company has developed the integral anti-electricity-theft anti-misoperation type three-phase four-wire and three-phase three-wire terminal block boxes to take the place of traditional DFY series terminal box, they have functions of electricity-theft prevention, anti-misoperation, convenient for field detection, the products now have been fully popularized and launched onto the market. |
