Microcomputer relay protection testing system/tester

Microcomputer relay protection testing system/testerAdopting a designed heat dissipation structure to ensure adequate ventilation. And it can simultaneously detect phenomena that endanger the safety of the device, such as overcurrent, overvoltage, overload, short circuit, high temperature, abnormal data, etc. Even if there is an operational error, it will not damage the device. In addition, when a danger signal such as external voltage enters the tester through the terminal, the device alarm indicator light turns red and automatically cuts off the power amplifier.

The microcomputer relay protection testing system is a new type of miniaturized microcomputer relay protection tester, which is based on summarizing the advantages and disadvantages of similar products at home and abroad, widely listening to user opinions, and fully utilizing modern microelectronics technology and power electronics technology. It adopts popular DSP and switch amplifier technology, and has excellent single machine independent operation function. Coupled with PC software, it can be connected to a computer for operation, adding to its functionality. However, its volume and weight are only half of traditional testers.

Microcomputer relay protection testing system/testerIt has a standard six phase current and six phase voltage output simultaneously, with a current of 30A/phase and a voltage of 125V/phase. Six phase current parallel connection can reach 180A. It can be used to test various traditional relays and protection devices, as well as various modern microcomputer protections, especially for transformer differential protection and backup automatic switching devices, making testing more convenient.

Has the following advantages:
1. Using a high-speed and high-performance digital control processor as the control microcomputer, the software applies a dual precision algorithm to generate high-precision waveforms of any phase
2. By using a high-speed high-level D/A converter, the accuracy and linearity of current and voltage across the entire range are ensured.
3. There is an adjustable DC power output on the chassis bottom board, divided into two levels of 110V and 220V, which can be used as an auxiliary power supply for on-site testing.
4. The device adopts a 320 × 240 dot matrix high-resolution blue backlit LCD display screen as the display.
5. The power amplifier circuit adopts imported high-power high fidelity modular power devices as the power output stage, combined with carefully and reasonably designed heat dissipation structure, with sufficient power redundancy and thermal capacity.
6. The classic Windows XP operating interface is user-friendly and easy to operate. In order to facilitate user use, a large number of keyboard shortcuts have been defined, making the operation "one click in place".
