Problems solved by technology

There are two types of European-style box transformer structure: one is the mesh-shaped structure. The disadvantage of this structure is that the high-voltage and low-voltage incoming and outgoing lines are connected to the high-voltage and low-voltage cabinets from the top of the transformer, so that the high-voltage incoming lines are exposed, and the transformer The design temperature rise of its own coil is high, so the load capacity of the transformer

Embodiment Construction

[0017] The present invention as figure 1 , 2 , 3, it is connected with the upper computer, including high-voltage / transformer cabinets and low-voltage cabinets arranged in a Japanese structure. The high-voltage / transformer cabinets are equipped with terminal-type or ring-net-type ring network cabinets and transformers; Intelligent controller, metering circuit, and reactive power compensation circuit connected to the host computer.

[0018] The intelligent controller mainly includes the interconnected main control module, measurement module, display module, switch control module, and functional modules such as fault recording and grounding test;

[0019] The single-chip microcomputer is set on the main control module, and each functional module is directly controlled by the single-chip microcomputer and works relatively independently;

[0020] The measurement module uses the AC sampling method to collect and process the current and voltage input signals of the three-phase AC ...

Abstract

The invention relates to an intelligent prefabricated substation, in particular to a set of distribution devices for the transformation and distribution field. The substation comprises a main control module, a measurement module, a display module, a switch control module, a fault recoding function module, an earthing test function module and other function modules. A single chip microcomputer is arranged on the main control module. The functional modules are controlled by the single chip microcomputer directly and work relatively independently. The measurement module collects and processes the data of the current and voltage input signals of a three-phase AC circuit through an AC sampling method, measures current, voltage, active power, reactive power, power factor, phase, frequency and electric energy parameter, stores measured data in EEPROM for an upper monitor to read and analyze for later processing. The switch control module is provided with a relay, monitors the state of switches, receives switch control commands sent by the upper monitor and makes the corresponding switch work by controlling the relay. The invention has the advantages of convenient manufacture and quick maintenance.

Description

technical field [0001] The invention relates to a complete set of power distribution equipment used in the field of power transformation and distribution, in particular to a compact 24KV high-voltage / low-voltage pre-installed box substation equipment. Background technique [0002] At present, there are mainly two structural types of box-type substations at home and abroad: one is American-style box-type substation, and the other is European-style box-type box-type substation. There are two types of European-style box transformer structure: one is the mesh-shaped structure. The disadvantage of this structure is that the high-voltage and low-voltage incoming and outgoing lines are connected to the high-voltage and low-voltage cabinets from the top of the transformer, so that the high-voltage incoming lines are exposed, and the transformer The design temperature rise of its own coil is high, so the load capacity of the transformer is poor, and it is easy to burn out the transfo...
