Embodiment Construction

[0027] In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. It should be noted that the components illustrated in the drawings are not necessarily drawn to scale. The present invention omits descriptions of well-known components and processing techniques and processes to avoid unnecessarily limiting the present invention.

[0028] Such as figure 1 , figure 2 with image 3 As shown, a distributed power grid-connected power distribution cabinet of the present invention includes a cabinet and a distributed power access control device and a temperature and humidity adjustment device arranged in the cabinet. The bottom of the cabinet 1 is provided with a base 2 and a cabinet cover 3 is provided above the top; the base 2 is set 0.3-0.6m above the ground, which can effectively prevent the power distribution cabinet from being corroded by rainwater and increase the power distribution The life of the cabinet ...

Abstract

The invention discloses a distributed type power supply grid-connected power distribution cabinet. The power distribution cabinet comprises a cabinet body, a distributed type power supply access to power grid control device which is arranged inside the cabinet body, and a temperature and humidity adjusting device. The distributed type power supply access to power grid control device comprises a grid-connected inverter, a knife switch, a voltmeter, an ammeter, a line inlet side breaker, a surge protection device, an isolated island protection device, an intelligent gateway electric energy meter, and a line outlet side breaker which are successively arranged in a series connection and are accessed between a distributed type power supply and a commercial power grid; the temperature and humidity adjusting device comprises a temperature detection device, a humidity detection device, a controller, a cooling and dehumidification device and a power supply module. The temperature detection device and the humidity detection device are arranged inside the cabinet body and are connected with the controller. The controller is connected with the cooling and dehumidification device arranged on the cabinet body. The power supply module provides working power supply. By means of the power distribution cabinet, the safety problem of traditional distributed type power supply being incorporated in commercial power grid is solved, and effective cooling and dehumidification can be performed to power distribution cabinet interior so that the service life of power distribution cabinets can be prolonged.

Description

Technical field [0001] The invention relates to a power distribution cabinet, in particular to a distributed power grid-connected power distribution cabinet, belonging to the technical field of power distribution network safety. Background technique [0002] Today’s distributed power sources mainly refer to internal combustion engines (IC) using liquid or gas fuels, microturbines (Microturbines), various engineering fuel cells (FuelCell), solar power plants, and wind turbines. On-site or close to the power-consuming site to meet the needs of specific users, support the economic operation of the existing distribution network, or meet the requirements of both aspects. The proximity to users improves service reliability and power quality. The combination of technological development, public environmental policies and the expansion of the power market has made distributed power generation an important energy choice in the new century. [0003] Distributed power sources need to input ...
