In the resistance unit of resistor, the screw rod being fixedly connected with, metal profile are by nested porcelain piece and resistor disc insulation, between the screw rod of resistance unit layer and metal profile by insulated column mutually insulated, when energising operation, non-resistance original paper is fixedly connected with the metal guide of screw rod and metal profile and knows from experience with change in voltage generation current potential, i.e. floating potential.To super (spy) hv filtering device resistor, because system voltage is very high, the floating potential in resistor box, can discharge with change in voltage, flashover, thereby makes failure of insulation.For this reason, when design, super (spy) hv filtering device resistor of manufacture, must strengthen the distance between resistance unit and supportive conductors, strengthen current potential between each metallic conductor and the insulation spacing of electric discharge and flashover does not occur and require can not have floating potential in resistor box.Therefore the overall dimension of resistance unit is huger, thereby it is also huger, heavy to make to surpass the resistor box of (spy) hv filtering device resistor.
The i.e. assembling form of version of the resistance unit of the resistor that general supply power voltage is not high is: after resistor disc being stringed together with nested porcelain piece with the screw rod being fixedly connected with, by metal profile, screw rod is supported.Several resistor discs just form a resistance unit layer by screw rod, nested porcelain piece, metal profile like this.After several resistance unit layers are separated by insulated column, pile up and get up to form one group of resistor, some groups of resistors form a resistor box.Several resistor boxs form complete filter resistor.In resistor box, in resistance unit layer, between resistor disc, with argon arc welding, weld, the resistance of resistance unit interlayer connects with copper bar, is finally unified into the resistance of whole resistor box.
Eliminate the floating potential of metallic conductor screw rod, resistor box and cabinet conductor in resistor box, make that resistor box insulation is reliable, safety, overall dimension is little, lightweight, is that super (spy) high-pressure system and remote conveying power transformation filter resistor field have technical problem to be solved.
