Transverse integrated pole-mounted transformer table with integrated power transformation box and comprehensive power distribution box

Abstract

The invention relates to a transverse integrated pole-mounted transformer table with an integrated power transformation box and a comprehensive power distribution box. The transverse integrated pole-mounted transformer table comprises a high-voltage inlet wire portion, a power transformation portion and a low-voltage power distribution portion. The high-voltage inlet wire portion and the low-voltage power distribution portion are arranged in the left-right directions to form a transversely arranged integrated structure; high-voltage sleeves and low-voltage sleeves are arranged above a voltage transformation box of the power transformation portion; low-voltage sleeves at the rear of the comprehensive power distribution box of the low-voltage power distribution portion are sealed by cover plates, are subjected to power distribution by the aid of the comprehensive power distribution box, are led out, and are directly inserted into a power transformation oil tank, so that the power distribution fault rate of the power transformation oil tank can be reduced, the power failure time can be shortened, low-voltage cables can be directly saved, and loss of power distribution districts can be reduced; a heat-insulation steel plate is arranged between the power transformation box and the comprehensive power distribution box and is subjected to heat-insulation paint brushing treatment, and heat can be externally dissipated via heat dissipation channels. The transverse integrated pole-mounted transformer table has the advantages that the transverse integrated pole-mounted transformer table is transversely arranged, accordingly, requirements of distribution network assembly development trend can be met, the power distribution network engineering quality can be improved, and the district building construction and operation and maintenance management work benefits can be increased.

Description

technical field [0001] The invention relates to the technical field of power transformation and distribution equipment, in particular to a horizontally integrated post-mounted transformer platform composed of a power distribution box and a comprehensive power distribution box. Background technique [0002] At present, the transformers and JP-type integrated distribution boxes on the 10kV pole-mounted substation are installed independently. The installation time is long, the installation accuracy is not high, and many angle irons, cross arms, hoops, and iron accessories are used, which is time-consuming and labor-intensive, and the operation and maintenance workload is heavy. The low-voltage cables from the transformer to the JP-type integrated distribution box are pulled independently, and there are many problems with the pile head during operation, which is likely to cause power distribution accidents, and does not meet the company's requirements for implementing refined ma...

Problems solved by technology

[0004] For example: "Three-in-one transformer device" (China, CN201520237101.0), a three-in-one transformer device, including a transformer, a series reactor, six static capacitors and other components, of which the six static capacitors are composed of their positive poles and six The electromagnetic contactors are connected, and the coil ends of the six electromagnetic contactors are connected to the outlet end of an automatic power factor adjuster. The main function of the static capacitor is to improve the power system power factor, thereby absorbing ineffective power when it is under load , and reduce the overvoltage, so that the voltage of each bus can be within a reasonable range, so that it can absorb invalid power and control the system voltage at off-peak time, form a normal voltage within an appropriate range, and filter harmonic convex waves, hidden voltages, Current limiting to form a good quality of electricity consumption, the three-in-one transformer device in the above-mentioned prior art mainly includes a transformer, a series reactor, six static capacitors and other components; ZYB-12 / 0.4-800 box-type substation, the overall According to the requirement that the high-voltage room, transformer room, and low-voltage room are independent of each other, the design adopts the "product"-shaped layout; the integrated power transformer, the transformer body is installed in the lower part of the lower oil tank and the upper oil tank, and the high-voltage metering transformer is located in the upper oil tank. There is room for improvement
