Reactive power compensation and voltage adjustment device for distribution network

Abstract

The invention relates to the technical field of reactive power compensation and voltage regulation for a distribution network, and discloses a reactive power compensation and voltage adjustment devicefor a distribution network. The reactive power compensation and voltage adjustment device for a distribution network comprises a reactive power compensation cabinet, a protective door and a receivingplate; a hydraulic rod is fixedly mounted on the bottom portion of the inner cavity of the receiving plate, the pushing end of the hydraulic rod is fixedly connected with the middle portion of the bottom end of the receiving plate, two fixing rods are fixedly mounted on the top portion of the receiving plate, the top end of the fixing rod is fixedly connected with the middle portion of the bottomend of a mounting bottom plate, the mounting bottom plate is slidably arranged in an inner cavity of a moving slot, and the moving slot is opened on the middle portion of a fixing substrate. According to the reactive power compensation and voltage adjustment device for the distribution network, with the combination of the hydraulic rod, the receiving plate and the fixing rods, a capacitor mountedon the top portion of the mounting bottom plate is pushed, so that the capacitor slides between the inner cavities of the moving slot and the receiving plate, and stretches the connecting wires at the top end of the capacitor, thereby prevent the connecting wires from bending.

Description

technical field [0001] The invention relates to the technical field of reactive power compensation and voltage adjustment of a distribution network, in particular to a device for reactive power compensation and voltage adjustment of a distribution network. Background technique [0002] The distribution network refers to the power network that receives electrical energy from the transmission network or regional power plants, and distributes it locally or gradually by voltage to various users through distribution facilities. It is a network composed of overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensators and some ancillary facilities. It plays an important role in distributing electric energy in the power network. During the entire operation of the distribution network, reactive power Compensation and voltage adjustment work occupy an extremely important position.

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a distribution network reactive power compensation and voltage adjustment device, which can accurately analyze voltage feedback data, make the installation of parallel capacitors in reactive power compensation cabinets adjustable, and prevent parallel capacitors from being connected The advantages of wire bending and other advantages solve the need to use matching reactive power compensation cabinets in the existing reactive power compensation work, and at the same time need to install parallel capacitors in the reactive power compensation cabinets. Complete the work of reactive power compensation and voltage adjustment. During the installation of the capacitor in the reactive power compensation cabinet, because there is no structure that can adjust the installation height, it is easy to bend the connecting wires after installation, and it is easy to damage the outer skin of the wires and At the same time, there is a great potential safety hazard in the normal operation of the connecting wires. At the same time, the design of the common voltage adjustment process is relatively simple. It mainly performs reactive power compensation and voltage adjustment after detection and analysis, because there is no effective data analysis. Analysis and processing bring certain difficulties to the maintenance of power system stability
