Embodiment Construction

[0022] The present invention will be further described in detail below with reference to the drawings and specific embodiments, but it is not intended to limit the present invention.

[0023] The patent of the invention provides a method for increasing the secondary output capacity of a capacitive voltage transformer.

[0024] Such as figure 1 As shown, the secondary output capacity is increased by controlling the primary winding of the intermediate transformer. The method is mainly composed of the following components, a detection device that detects the secondary load, and a component that controls the action of the auxiliary winding. This part can be completed by a static current relay. The input or removal of the auxiliary winding is controlled by the normally open and normally closed electric shock of the quiescent current relay. The parameters of the auxiliary winding are determined according to the above formula. Note: Refer to the implementation content of the invention p...

Abstract

The invention provides a method of increasing a secondary output capacity of a capacitor voltage transformer. A secondary winding of the capacitor voltage transformer is provided with a secondary load detection apparatus. According to an acquired secondary load, a number of turns of a transformer primary winding is adjusted, a number of turns of a reactor is compensated, and a capacitor voltage transformer transformation ratio and a reactance are adjusted so that a capacitor voltage transformer output capacity is increased and accuracy of a capacitor voltage transformer product satisfies a standard requirement from a light load to a full load.

Description

【Technical Field】 [0001] The invention belongs to the field of capacitive voltage transformers, and relates to a method for adjusting primary loop parameters according to load conditions, and in particular to a method for improving the secondary output capacity of a capacitive voltage transformer. 【Background technique】 [0002] The capacitive voltage transformer is composed of a capacitive voltage divider and an electromagnetic unit, and is used to detect the primary side voltage in the power grid. Among them, the electromagnetic device is an important component, which has a great influence on the accuracy and stability of the product. The electromagnetic device is composed of intermediate transformer, compensation reactor, damping device, etc. With the improvement of users' requirements for product accuracy levels, secondary loads, etc., products can only be achieved by increasing the rated capacitance and increasing the rated intermediate voltage. This not only increases the...
