Abstract
The utility model relates to a resistor, in particular to an open precharge high-power resistor, which can solve the problems in the prior open precharge high-power resistor, such as complex structure, difficult processing, high cost and the like. The open precharge high-power resistor includes a threaded ceramic base body, a resistance alloy tape wound around the base body and electric connection brackets at the two ends of the base body, wherein each electric connection bracket is formed by an end cap sleeved at one end part of the base body and connected with the resistance alloy tape which is wound around the base body, and a fixed claw fixed with the end cap. The open precharge high-power resistor provided by the utility model simplifies the structure of the electric connection brackets on the basis of the prior open precharge high-power resistor, so that the structure of the electric connection brackets is easier to process, and the manufacturing cost of the whole product is reduced. The open precharge high-power resistor can be mainly applied in electrical equipment with higher requirements on electrical protection degree and output power degree.
Description
Technical field
The utility model relates to resistor, is specially a kind of open type precharge Power Resistor.
Background technology
Open type precharge Power Resistor is mainly used in the higher electric equipment of electrical equipment degree of protection and power output class requirement.Be to reduce HPC high power DC in the direct current intermediate link and support the higher di/dt current changing rate that capacitor produces and consider that direct current supports useful life, the reliability of capacitor in pre-charge process, and satisfy the dynamic responding speed of whole electric equipment and particular design.The present main dependence on import of open type precharge Power Resistor.Open type precharge Power Resistor by the screw thread ceramic matrix, adopt canoe to be fixed in the electric resistance alloy band on the matrix, the parts such as electrical connection support at matrix two ends are formed.Existing open type precharge Power Resistor structural design is unreasonable, and it is electrically connected supporting structure complexity, processing difficulties, cost height.
Summary of the invention
The utility model provides a kind of open type precharge Power Resistor of new structure in order to solve problems such as existing open type precharge Power Resistor complex structure, processing difficulties, cost height.
The utility model is to adopt following technical scheme to realize: open type precharge Power Resistor, comprise the screw thread ceramic matrix, be wound in the electric resistance alloy band on the matrix and the electrical connection support at matrix two ends, be electrically connected support by being placed in matrix end and the end cap that is connected with electric resistance alloy band on being wound in matrix and constituting with fixed claw that end cap is fixed.During use, being electrically connected support and both having played the support fixation resistor, is again the splicing ear of resistor.
Open type precharge Power Resistor described in the utility model has been simplified the structure that is electrically connected support on the basis of existing open type precharge Power Resistor, make it be easier to processing, and reduced the entire product manufacturing cost.This open type precharge Power Resistor is mainly used in the higher electric equipment of electrical equipment degree of protection and power output class requirement.
