Product descriptions from the supplier
The drive module is used in conjunction with the circuit breaker, serving as a control and online monitoring device for the circuit breaker system. The housing of the drive module is made of aluminum alloy, which can effectively shield electromagnetic interference, including five unit circuits：
Switching power supply unit: Converts the external auxiliary power supply into the power source used by the internal circuit.
Charging circuit unit: Stores electrical energy for the closing and opening capacitors.
Discharge circuit unit: Injects positive excitation current or reverse demagnetization current into the excitation coil of the circuit breaker mechanism to magnetize or demagnetize the mechanism.
I/O interface unit: It is used to receive the opening and closing commands as well as the input of the circuit breaker status.
Control Unit: Monitors and controls the operation of the entire circuit breaker.
Basic function
Provide the excitation current for closing operation
Provide de-magnetizing current for opening operation
On-line monitoring
Alarm for abnormal movement of auxiliary switch
Manual trip alarm
Anti-jump and locking function
The drive module itself has a function of anti-jump locking
application

What Are the Factors Influencing the Impact of Lightning on 10kV Distribution Lines?1. Induced Lightning OvervoltageInduced lightning overvoltage refers to the transient overvoltage generated on overhead distribution lines due to nearby lightning discharges, even when the line is not directly struck. When a lightning flash occurs in the vicinity, it induces a large amount of charge on the conductors—opposite in polarity to the charge in the thundercloud.Statistical data shows that lightning-related faults caused by induced overvoltages account for approximately 90% of total fauEcho11/03/2025 -
THD Measurement Error Standards for Power SystemsError Tolerance of Total Harmonic Distortion (THD): A Comprehensive Analysis Based on Application Scenarios, Equipment Accuracy, and Industry StandardsThe acceptable error range for Total Harmonic Distortion (THD) must be evaluated based on specific application contexts, measurement equipment accuracy, and applicable industry standards.

Why is it difficult to increase the voltage level?The solid-state transformer (SST), also known as a power electronic transformer (PET), uses voltage level as a key indicator of its technological maturity and application scenarios. Currently, SSTs have reached voltage levels of 10 kV and 35 kV on the medium-voltage distribution side, while on the high-voltage transmission side, they remain in the stage of laboratory research and prototype validation. The table below clearly illustrates the current status of voltage levels across different appliEcho11/03/2025 -
Compact Air-Insulated RMUs for Retrofit & New SubstationsAir-insulated ring main units (RMUs) are defined in contrast to compact gas-insulated RMUs. Early air-insulated RMUs used vacuum or puffer-type load switches from VEI, as well as gas-generating load switches. Later, with the widespread adoption of the SM6 series, it became the mainstream solution for air-insulated RMUs. Similar to other air-insulated RMUs, the key difference lies in replacing the load switch with an SF6-encapsulated type—where the three-position switch for load and grounding isEcho11/03/2025 -
Standards and Calculation of LTAC Test for Power Transformers1 IntroductionAccording to the provisions of the national standard GB/T 1094.3-2017, the primary purpose of the line terminal AC withstand voltage test (LTAC) for power transformers is to evaluate the AC dielectric strength from the high-voltage winding terminals to ground. It does not serve to assess inter-turn insulation or phase-to-phase insulation.Compared with other insulation tests (such as full lightning impulse LI or switching impulse SI), the LTAC test imposes a relatively more stringenOliver Watts11/03/2025 -
