The utility model provides a new type of distribution network low voltage user single-phase metering box, including a table box body, an electric energy meter in the body, an observation hole in the body of the table box, a transparent window on the observation hole, a flame retardant mechanism in the lower part of the body of the table box, and the flameproof mechanism on the side of the body of the table box, and the flame retardant mechanism includes the table. The inlet air hole is arranged in the lower part of the box body. The inlet air pipe is connected with the argon gas tank through the gas supply pipe, the argon gas tank is arranged on the electromagnetic valve. The explosion protection mechanism includes the exhaust hole arranged on the side of the table box body, the outside of the body of the table box is connected with the exhaust pipe connected with the exhaust hole, the end of the exhaust pipe is set with the expansion air bag, and the embrittlement baffle is set in the exhaust hole. The utility model can protect the table box, fill the inert gas into the interior before the table temperature rises sharply, reduce the probability of burning and fire, and set up explosion-proof mechanism to avoid the explosion of the table box in the case of the rapid heating up of the table box, and protect the surrounding environment and the people very well.

一种新型配网低压用户单相计量表箱
本技术涉及电能表箱
,具体涉及一种新型配网低压用户单相计量表箱。
技术介绍
单相电能表箱是计量电能消耗、计量电费多少的必备设备,其安全正常运转直接关系到供电企业的经济利益和供电企业在广大用电客户心目中的形象。表箱内部各元部件呈紧凑型布局,箱内检修空间狭小,增大了出现短路现象的机率,短路时产生的急剧高温使得表箱内外形成气压差,使短路产生的电弧熔渣、火花等有害物质急速从表箱门及通风孔处喷溅而出,对检修人员造成伤害,也会对原有表箱内的设备造成二次损害。公开号为206161709U的技术公开了一种用于配电网居民用户端的可灭火报警电能表箱,包括箱体和箱门;箱体上设置有防爆窗口;箱体内设置有总控制器、信号发射器、多个温度传感器及火焰传感器的集成模块和多个风扇;总控制器分别与信号发射器、集成模块和风扇电连接;箱体外侧设置有报警器,报警器与总控制器电连接;箱体内部顶端设置有灭火包。本技术一方面当集成模块检测到箱体内温度过高或有火焰时,总控制器控制信号发射器提醒人们采取措施,控制报警器发出警报,控制风扇向外抽风,形成近似真空,极大程度减少氧气 ...
