Description

Technical Field

[0001] The utility model relates to the technical field of reactive power automatic compensation devices, in particular to a reactive power automatic compensation device capable of adjusting voltage. Background Art

[0002] In my country, the power system has very high requirements for voltage stability, because voltage stability directly affects the normal operation and power quality of the power system. With the continuous expansion of the power system scale and the continuous increase of power load, the voltage stability problem has become more and more prominent. In order to solve this problem, the voltage-adjustable reactive power automatic compensation device came into being.

[0003] There are two main types of reactive power compensation devices that can adjust voltage: static reactive power compensation devices (SVC) and dynamic reactive power compensation devices (SVG). The working principles of these two types of compensation devices are similar, both of which adjust the output of reactive power to achieve voltage regulation.

[0004] Some reactive power automatic compensation devices are installed above utility poles and directly connected to the circuit system. Devices installed on utility poles need to be supported by brackets. During installation, existing brackets are supported by the friction between the brackets and the utility poles. The friction is increased by the action of force. During long-term support, the friction may be reduced due to loose bolts, which may lead to the inability to stably support the device.
