Even after purchasing a very goodseries resonant device, there are still many details to pay attention to when using it, such as installation being one of them. Finding a suitable installation method can also have great value for the entire use. Let's take a look at what to pay attention to when installing series resonance?
Firstly, it is necessary to understand whether there is a malfunction. Before the manufacturer sells their product to the market, there will also be corresponding performance and quality testing. However, during transportation, its quality and performance may be slightly affected due to external factors. Before installation, it is necessary to check whether the packaging of the series resonance device purchased is complete, whether the spare parts inside are complete, and whether the performance has changed. These are all things that need to be understood before installation to ensure a smooth installation process and precise data analysis capabilities during use.
Secondly, although the installation method is not very difficult, for safety and performance stability reasons, it is necessary to read the user manual and understand how to install it to ensure that the various components of the series resonance are perfectly combined to achieve higher detection efficiency. If you are not familiar with the user manual, you can also call the after-sales service hotline of the series resonance manufacturer in a timely manner, and there will be professional staff who can provide you with a more detailed answer. Tell everyone how to install and debug, which can ensure more convenient use in the future and avoid other problems.
Thirdly, the installation and wiring process
1. Reliable grounding! Reliable grounding! Reliable grounding!
This is the most important one. Multiple bare copper wires with a sufficiently large cross-sectional area (usually not less than 25mm ²) must be used to firmly connect the grounding terminals of all system components (frequency converter, excitation transformer, reactor, voltage divider) to the same grounding grid. The grounding resistance must meet the requirements to ensure that energy can be quickly released in the event of discharge or breakdown, ensuring personal and equipment safety.
2. Correct wiring sequence:
Follow the principle of 'grounding first, wiring later'. Ensure that the power supply is completely disconnected before all wiring is completed.
Low voltage side wiring: Connect the measurement signal lines of the variable frequency power supply, excitation transformer, and voltage divider correctly according to the manufacturer's instructions. Ensure that the input voltage is consistent with the requirements of the variable frequency power supply.
High voltage side wiring:
Reactor connection: Connect the reactors in series or parallel according to the calculated plan. The connecting wire should be straightened to avoid winding and reduce stray inductance. The connecting bolts must be tightened.
Forming a resonant circuit: Connect the high voltage output end of the excitation transformer to the lower end of the first stage reactor, and connect the upper end of the last stage reactor to the high voltage end of the test sample through a voltage divider.
Test sample connection: The low voltage end or shielding layer of the test sample should be reliably grounded.
3. Key installation points for key components:
Reactor: If stacked, ensure that the center of gravity is stable and aligned vertically. If necessary, use brackets or insulated bases to secure.
Voltage divider: A voltage divider is a standard capacitor, and its accuracy directly affects the accuracy of the test voltage. It should be placed vertically, and the connecting wire between the high-voltage end and the test sample should be as short as possible, and kept at a sufficient distance from the grounding body.
Excitation transformer: Pay attention to whether its input tap matches the variable frequency power supply and whether its output tap matches the calculated value.
All pressure equalization rings/covers must be installed in place to improve electric field distribution and prevent corona discharge.
This way, we can have a clear understanding of how to installseries resonanceto achieve better results, ensuring that we can feel its unparalleled superiority throughout the entire use.
