Abstract

The invention provides a capacitance-resistance module and a voltage divider including the capacitance-resistance module, and aims at solving the problem that resistive and capacitive components need to be high in processing precision due to the fact that both the resistive and capacitive components need to be fixedly connected to an installing plate. The capacitance-resistance module comprises at least two conductors arranged separately, resistive and capacitive components are arranged between two adjacent conductors, and at least one end of at least one of the resistive and capacitive components is connected to the corresponding conductor via a sleeve electric-connection structure. The length of at least one of the resistive and capacitive components can vary within certain range, the sleeve electric-connection structure can make up the not high processing precision of the at least one resistive and capacitive component, the resistive and capacitive components can keep a conductive connection state with the corresponding conductors, and the requirement for the processing precision of the resistive and capacitive components is lowered.

Description

technical field [0001] The invention relates to a resistance-capacity module and a voltage divider comprising the resistance-capacity module. Background technique [0002] In recent years, my country's UHV DC transmission projects have developed rapidly. DC voltage dividers are mainly used for the measurement of DC side pole busbars, neutral lines and neutral line voltages of high-voltage and UHV DC transmission projects to achieve unipolar and bipolar protection and protection. Control and fault recording. The DC voltage divider generally adopts the resistance-capacitance voltage division technology, and realizes the low-voltage signal of the secondary terminal through the series-parallel voltage division of the resistors and capacitors; however, with the increase of the high-voltage DC transmission voltage level (1100kV), the DC voltage division The requirements for the resistance-capacitance module of the voltage transformer are becoming more and more stringent. The inter...
