Resistor assembly: be fixed on the insulating part, comprise a plurality of interconnective resistive elements, the concrete quantity of this resistive element requires to confirm according to practical design;
Wiring tap: be located on the outer wall that supports outer container, connect resistor assembly, the quantity of wiring tap is at least two.
The cross section of described support outer container is that central angle is 90 ° fan-shaped.
Described support outer container is provided with the reinforcement that is used to improve mechanical performance, and the outer wall that supports outer container is coated with the carbon steel layer of paint.
Described resistive element is a steel disc formula resistive element, is equipped with contact pin on each resistive element, is fixed on the insulating part through this contact pin.
A kind of resistor that adopts above-mentioned fan-shaped resistance unit comprises:
The resistor main body: comprise a plurality of fan-shaped resistance units, constituting a cross section by a plurality of fan-shaped resistance units is circular resistor main body;

Described resistor main body comprises 4 fan-shaped resistance units.
Compared with prior art, the utlity model has following advantage:
One, reduce cost: novel fan-shaped resistance unit has been saved unnecessary special guiding device, and amount of parts is also less, and simple installation reduces the consumption of artificial and resource, helps the optimization of enterprises resource management, reduces cost.
Two, safe and reliable: as to match with circular blower fan by a plurality of fan-shaped circular configurations of forming; Even the two does not have special guiding device also can not reduce wind-cooling heat dissipating efficient; Almost be covered with the insulating part that supports outer container and can guarantee that not only electric insulation also can reduce the resistor hull-skin temperature; Make it durable in use, other equipment around can not influencing more can be to not injuring personnel.
Three, maintainability is good: the resistance unit disassembly process is convenient, reduces manpower consumption, reduces unexpected probability of errors.And identical fan-shaped resistance unit has interchangeability, only need pull down during maintenance work the resistance unit that will safeguard change resistance unit or the spare part of accomplishing maintenance work, can not influence the routine work of whole resistor.
