Abstract

The invention provides a 10 / 0.4 kV pole-mounted transformer substation low-voltage distribution box suitable for an oil and gas field station. The distribution box at least comprises a distribution box body, an isolating switch, a busbar, a post insulator, a lightning arrester, a current transformer, a circuit breaker, a fuse, a contactor, a power capacitor, an intelligent electric energy meter, avoltmeter, an indicating lamp, a voltage change-over switch, a capacitor fling-cut switch and a current and voltage wiring terminal. The front surface and the back surface in the distribution box body are separated by an insulating separator plate. And the isolating switch, the busbar, the fuse and the circuit breaker are sequentially arranged on the front bracket in the distribution box body from top to bottom. The low-voltage distribution box is simple in structure, standardized in installation, standardized in design and capable of achieving oil and gas field station power distribution andon-site reactive compensation functions, unifies standard installation methods of the 10 / 0.4 kV pole-mounted transformer substation low-voltage distribution box of the oil and gas field station, andfurther improves adaptability of the 10 / 0.4 kV pole-mounted transformer substation low-voltage distribution box of the oil and gas field station.

Description

technical field [0001] The invention belongs to the field of surface engineering construction of oil and gas fields, and in particular relates to a low-voltage distribution box suitable for 10 / 0.4kV pole-mounted substations in oil and gas field stations. Background technique [0002] Due to the load characteristics of some oil and gas field stations, not only the 10 / 0.4kV pole-mounted substation is required to supply power to the station, but also the pole-mounted substation is required to perform reactive power compensation on site. The current national standard atlas "Outdoor Transformer Installation" (04D201-3) distribution The electrical box scheme only has the distribution circuit scheme, and there is no standard installation method for integrating the distribution circuit and local reactive power compensation into one side of the distribution box. There are diversification in design, inconsistent on-site construction, confusing methods, and many problems. . Contents ...
