Program-controlled power signal testing device based on transformer

Abstract

The invention discloses a program-controlled power signal testing device based on a transformer. The program-controlled power signal testing device includes a cabinet body (100), a communication module (200), a testing assembly (300), an interface module (400) and a security module (500), wherein the communication module (200), the testing assembly (300), the interface module (400) and the security module (500) are arranged in the cabinet body (100). According to the program-controlled power signal testing device based on the transformer, design is reasonable, the structure is compact, the setcommunication module, testing assembly, interface module and the security module are matched with each other, thus multi-loop voltage, current, inputting, outputting, a power supply, power consumption testing and the like of a power distribution terminal can be simultaneously connected, multiple tests, such as voltage current precision and fault simulation, of the power distribution terminal aremonitored, practical performance of the program-controlled power signal testing device is greatly improved, using requirements are met, a set expansion device can provide a plurality of expansion interfaces, thus the basis is provided for inputting and outputting of the multi-loop current and voltage, using is simple, convenient and reliable, and promotion and using are facilitated.

Description

technical field [0001] The technical field of electric equipment that the present invention relates to, in particular, relates to a transformer-based program-controlled power signal testing device. Background technique [0002] The test cabinet integrates multiple functions such as protection, measurement, control, monitoring, communication, event recording, fault recording, and operation error prevention. Function, it can also independently complete small and medium-sized unattended substations of 110kv and below or as a complete set of protection and measurement monitoring functions for the medium and low voltage sides of 220kv and above substations; it can be installed locally or centralized screens; it is a substation It is an ideal intelligent equipment device for the comprehensive automation system of power stations such as power plants and power plants. [0003] However, the current transformer-based program-controlled power signal test device cannot meet the needs o...
