Series capacitors for use in power systems - Part 2: Protective equipment for series capacitor banks - General scope and purpose: This part of GB/T 6115 applies to protective equipment for series capacitor banks of 10 Mvar or more per phase. Protective equipment refers to the components and auxiliary equipment in the main circuit of a series capacitor device, which are part of the series capacitor device but are installed outside the series capacitor. The requirements for the series capacitor section are given in GB/T 6115,1-1998, and protection equipment is mentioned in 1.3 and 7.6 of GB/T 6115.1-1998. The protective equipment involved in this section includes the following items:—— Overvoltage protector; -- Protective spark gap; -- Nonlinear resistor (variable resistor); - bypass circuit breaker- Isolation switch; -- Current limiting damping equipment; -- Discharge reactor- Voltage transformer; - Current transformer—— Signal column—— Relay protection, control equipment, and platform to ground communication equipment. See Figure 1. Note. Due to the provisions of GB/T 6115.1-1998 and GB/T 6115.3 for fuses used in capacitors, this section does not discuss them. Chapter 3 provides the principles for the use and operation of series capacitors. Examples of fault conditions are given in Chapter 3. Examples of wiring diagrams using different overvoltage protection principles are given in section 2.1. The purpose of this section is to elaborate on the unified principles related to performance, testing, and ratings- Describe different types of overvoltage protectors-- Provide installation and operation guidelines
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problems100% inspection and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
