Background
The current limiting reactor is a very common electrical component, is usually applied to a power network, is essentially an air coil without magnetic conduction material, can be arranged into three assembly modes of vertical, horizontal and delta-shaped according to requirements, and can generate short-circuit current with larger value when short circuit occurs in a circuit, the reactor increases short-circuit impedance through self inductance, limits the short-circuit current, avoids the electrical component connected with the circuit from being damaged by high current, and in addition, the voltage drop on the reactor is larger, so that the effect of maintaining the bus voltage level is also played, the fluctuation of the voltage is smaller, and the running stability of electrical equipment on the circuit is improved.
In the prior art, as the voltage level is increased, the required current-limiting reactor level is higher, such as a 220kV current-limiting reactor, and the volume and the weight of the reactor are also larger. If the aluminum star frame is used, the star arm is easy to deform and bend because the aluminum star frame is not high in material strength in the production, hoisting and transportation processes. And when the circuit system is short-circuited, the short-circuit current flows through the current limiting reactor, and great electric power can be generated. Since the spider acts as an important component of the reactor, and acts as a bus bar, a support, and the like in the reactor, it is necessary to design a spider having high strength according to the needs of the reactor.
