  2. Structure characteristics
      The installation manners of equipment have kind of ground installation, suspended installation and pole-mounted installation, so it can satisfy needs of many service conditions.
      The equipment body is processed and welded by stainless steel plate with high quality and has beautiful appearance; Design for body is reasonable, because it fully consider the affection of equipment brought by outdoor circumstance and have realized the function of "Three Prevention and One Ventilation" (namely is rain & snow proof, corrosion-proof, prevent insects getting into, ventilative and heat-scattered. ); Mostly installation parts in box also adopt stainless steel and have good performance of corrosion-proof; there are enough cable sheath and cable hoop placed at incoming and outgoing hole.   
       The primary circuit scheme of equipment is complete, customer can neatly choose knife switch, knife fuse switch, circuit breaker and etc. to be as incoming and outgoing components according to their needs. The knife switch and knife fuse switch totally adopt NH-bus type fuse load disconnector and NH-bar fuse type load disconnector produced by Germany Wehnelt Electric System Company, the circuit breaker can adopt busbar commutator produced by
    Germany Wehnelt Electric System Company to make hang-connect type installation, it also can make normal fixed installation and use cable and lead connecting nip to carry out no-hole
 
connection of busbar.

 
Distribution busbar of equipment adopts 60mm,100mm busbar system from Germany Wehnelt Electric System Company and the distribution components can directly hang and connect on the busbar to realize no-hole connection of busbar, so it features of high standardization, safe and reliable, flexible and convenient, compact structure, reasonable wiring and convenient to install and disassemble
 
 
 
 
 
 
 
 
 


  1. Main components
  1. The equipment mainly adopts NH-bus type fuse load disconnector produced by Germany Wehnelt Electric System Company to be as incoming knife fuse switch or knife switch, please see table 7.1 for outline and main characteristics and see table 7.2 for main parameters.
 
 
Table 7.1 Main function characteristics of NH-bus type fuse load disconnector


 
Main function characteristics:
     
1,Can be with load-breaking and used in open;
2,Can use test pencil to test operation condition of fuse during operation;
3,With blade import and arc extinguishing device;
4,With mechanical lock device;
5,This switch can be installed with fuse to be as fuse type load disconnector and also can be installed with connecting blade to be as knife switch;
6,Unique drawer technique realize the exchange for upper and lower outgoing of bus type switch;
7,With protective parts to prevent getting an electric shock when operation with electricity;
8,Choose cable cover to realize seal when use incoming and outgoing cable;
9,Cover lock of fuse can lock switch cover to prevent opening optionally;
10,On cover of switch it has inspection hole with self closed;
11,Guide rail fixing plate realize the fast installation;
12,Can install signal switch to inspect close of switch cover;
13,Can be equipped with inspector for fuse;
14,Breaking capacity is 50kA;
15,Protection grade can reach to IP20.
