Detailed introduction

Product introduction

HCT3900 automatic backup tester can simulate the primary wiring of substations and power supply systems in various operating modes, and can intuitively display and simulate the secondary voltage, current and circuit breaker position signals of the line in various modes of automatic backup devices, and simulate abnormal conditions in various operating modes, such as: line power failure, main transformer failure, switch tripping, etc. At the same time, it automatically monitors and records the action process and related data of the automatic backup device, automatically processes the test data, draws test conclusions, and forms an experimental report. It can provide installation and testing basis for substations under construction, and provide solid evidence for the long-term operation, maintenance and management of line devices in substations that have been put into operation.

Functional features

Our company’s HCT3900 automatic backup tester is a professional-level automatic backup tester independently developed. It can simulate the automatic backup logic under various primary wiring modes through configuration software, and is suitable for testing the automatic backup power supply equipment of substations and power supply parts of various voltage levels. This tester can simulate various logical relationships between up to seven circuit breakers, six bus voltages and three line currents, such as the standby logic under two main transformers, three main transformers and four main transformers.

The machine is equipped with a high-precision three-phase test power supply, and the front panel uses a large-screen color touch LCD with a 640*480 dot matrix. The display content is clear and eye-catching, and the touch screen operation is simple and reliable.
