Relay Protection Calibrator - Yangzhou Darui
Darui Electric recommends for you
Relay Protection CalibratorThe tool is mainly composed of a voltage regulator and a phase shifter, which is bulky and heavy, with low precision, and can no longer meet the calibration work of modern microcomputer relay protection. With the continuous development of science and technology, microcomputer relay protection has been widely used in line protection, main transformer differential protection, excitation control and other fields, and substation comprehensive automation has become the mainstream. Therefore, the microcomputer relay protection tester will inevitably become an indispensable test tool for modern relay protection workers.
The relay protection calibrator is a new type of miniaturized microcomputer relay protection tester realized by summarizing the advantages and disadvantages of similar products at home and abroad, extensively listening to user opinions, and fully utilizing modern microelectronic technology and power electronic technology. It adopts internationally popular DSP and switching amplifier technology, and its standalone operation function is already very powerful. When paired with PC software, it can be connected to a computer for operation, making it even more powerful. Its volume and weight are only half of traditional testers, and the advanced design concept has brought this tester to a high level.
The relay protection calibrator adopts an advanced structure that can operate independently as a standalone unit or be connected to other computers. The host is equipped with a high-performance industrial computer and a high-speed digital signal processor, a true 16-bit DAC module, a new modular high-fidelity high-power amplifier, and comes with a TFT true color LCD display and an embedded microcomputer keyboard. It can be operated independently or connected to a laptop for operation. It has powerful operation functions, small size, and high precision. It not only has the superior performance and advanced functions of large testers, but also the compactness, flexibility, ease of operation, and high reliability of small testers.
Relay Protection CalibratorProduct features description:
1. The relay protection calibrator can calibrate various on-site relays, protections, and safety automatic devices, and can simulate various complex transient and conversion faults for whole-set tests.
2. It can save test data in real time, display vector diagrams, draw various characteristic curves, and print reports online.
3. Various fault simulation programs can truly simulate and replay various actual faults, transient processes, system oscillations, and reclosing action behaviors on site.
4. The relay protection calibrator is divided into two circuits: the main circuit and the auxiliary circuit. The main circuit is adjusted by a large knob, and the auxiliary circuit is adjusted by a small knob. The main circuit controls the output of various quantities through the "output selection" button switch on the panel, and each time a different output is switched, the digital voltage/current meter on the instrument can automatically monitor its output value.
5. It can conveniently test standby power supply automatic switching devices and microcomputer differential protection devices, and provide targeted calibration programs for various relays. The powerful functional test software can also provide automatic test procedures for complete sets of microcomputer protection and automatic devices with multiple calibration and search methods: line protection, differential protection, impedance protection, low frequency, synchronization, standby power supply automatic switching, etc.
