Zc-650 wireless relay protection vector analyzer is a distributed wireless synchronous instrument for measuring volt ampere phase electrical parameters. It is composed of two handheld measuring terminals. When each handheld terminal is used separately, it can be used as a three-phase volt ampere phase meter. When the two sets are used at the same time, they can measure six voltage, six current amplitude, phase and other parameters synchronously. The synchronous measurement phase error is within 0.5 °, which is very suitable for transformer differential protection vector analysis and bus differential protection vector analysis.
When using zc-650 wireless relay protection vector analyzer, the following safety precautions shall be noted:
1. In order to avoid possible dangers, this product can only be used within the specified range. Only qualified technicians can carry out maintenance and operation.
2. As a safety measure, the instrument is equipped with protective grounding terminal. Before the test, the grounding terminal on the side of the device shall be reliably grounded.
3. Prevent falling: do not place the instrument on an unstable platform or desktop to prevent the instrument from falling and damage.
4. Use appropriate power cord: use 220VAC, 50 / 60Hz power cord with current of 10a and above.
5. Ensure good heat dissipation: the fans and ventilation holes on the side of the instrument are set for ventilation and heat dissipation, and do not block them.
6. Prevent short circuit: do not let any foreign matter fall into the chassis to avoid short circuit.
7. Connect and disconnect correctly: do not connect or disconnect the test wire when the equipment is under test.
8. Do not operate without cover plate: if the cover plate or panel has been removed, do not operate this product.
9. Use appropriate fuse: 12a fuse is used for this equipment.
10. Avoid contact with exposed circuit and live metal: do not touch exposed contacts and parts when the product is powered.
11. Do not operate in case of suspected fault: if the product is suspected to be damaged, please check it by the company's maintenance personnel and do not continue to operate.
12. Operating environment: do not operate in humid or explosive environment.
13. This instrument is a precision electronic instrument. Please pay attention to prevent the high temperature environment such as sun exposure when using outdoors, and do a good job in blocking the sun and ventilation, so as to prevent the instrument from overheating or reducing the measurement accuracy.
ZC-650 The wireless relay protection vector analyzer completely solves the problem of distributed synchronous measurement in the substation, without GPS, without laying cables to introduce the reference voltage, avoiding the PT secondary short circuit caused by cable insulation or operation problems. It is simple and practical, and is suitable for occasions without reference voltage, such as bus protection panel with 2 / 3 wiring, terminal box of outdoor current transformer, intelligent transformer The CT signal of differential protection before station merging unit can greatly improve the work efficiency of multi interval phasor measurement in the whole station, which is worth purchasing.
