Described rear chamber arranges two chambers up and down that are divided into by horizontal baffle, described current transformer is positioned at the bottom chamber of rear chamber, total fuse is positioned at the upper chamber of rear chamber, described residual current action breaker is placed in the top in front chamber, and shunting fuse is placed in the bottom of front chamber.
The upper chamber of described rear chamber is separated into two chambers in left and right, settles total fuse in one of them chamber, settles intelligent terminal in another one chamber; The bottom chamber of described rear chamber is also provided with collection electric energy meter.
Between described metering instrument transformer and the first inlet wire branch road, be serially connected with lightning arrester, the other end ground connection of described lightning arrester.
Described lightning arrester and total fuse are positioned at same chamber.
Described residual current action breaker is electromechanical residual current action breaker.
The utlity model has following advantage:
1, body structure arranges rationally, and appliance component is more single, and space hold is little, keeps in repair easyly, and goods and materials declare that dispensing is simple and cost is low;
2, there is shunting fuse (NTO), also just had obvious cut-off point, meet safety requirement;
As long as 3, along separate routes outlet want interruption maintenance pull open shunting fuse (NTO) just can, do not affect other loop power supply, improved power supply reliability, scientific and reasonable;
4, because there being shunting fuse (NTO), while there is electric leakage, moving attendant can be by looking into electricity mutually, and looking up the fault point is efficient and convenient, to operation maintenance, brings great convenience, has improved good service, has reduced O&M personnel's labour intensity;
5, meet the requirement to rural power grids intellectualized reconstruction upgrading expansion management in the future of Guo Wang company.
6, the electromechanical residual current action breaker adopting possesses high-performance, long-life, high breaking capacity, charged minor tripping function, residual current protecting adopts muting sensitivity, time lagged type band single shot reclosing function, and possesses and can match measurement, demonstration, the storage of information, the function of communication;
7, wire inlet-outlet is all arranged on the bottom of casing, and the top of casing is sealed completely, good water-proof effect.
