Liaoning Yingkou Insulation Monitor Original In Stock

The type insulation monitor is the third generation insulation monitor developed by our company for the characteristics of large distributed capacitance, high grid voltage, and complex grid in mining, metallurgy and other power grids. Compared with the early insulation monitor, the type intelligent insulation monitor has new features. An independent alarm point reaches an independent insulation resistance setting value and can alarm output. It has a remote test reset function and an analog output function. This type of product can completely replace the advanced European and American imported models and can be used in AC and DC power grids.
Plastic oil drilling rig electronic control system ground detection application -

The power configuration, output characteristics, control operation and protection functions of the oil drilling rig electronic control system meet the operating parameters of oil drilling rigs at various depths. Performance and drilling process requirements. Explosion-proof, shock-proof, moisture-proof and fire-proof measures are adopted to meet the requirements for safe operation. The system failure downtime rate that affects drilling operation time is less than. Generally, the diesel generator set is connected to the grid through the control cabinet of the generator set in the system, and AC power is output to the AC busbar
. The drive system adopts a fully digital vector control AC variable frequency speed regulating device. The rectifier unit converts the AC power on the AC busbar into DC power, outputs it to the public DC busbar, and then the inverter unit converts the DC power on the DC busbar into AC power with continuously adjustable voltage and frequency, using a one-to-one method. The control mode drives the AC variable frequency motor.
In this process, a fault ground detection system is required. A fault ground detection system is required to detect AC ground faults. In addition, one ground fault test button is required (mainly used to determine whether the indicator light is burned out when the ground fault indicator light is on). A grounding indication is also required. For this purpose, we designed and selected the second-generation insulation monitor model launched by Dongguan Qianbo Electronic Technology Co., Ltd. This type of insulation monitor has greater versatility, applicability and more powerful functions. It can be used universally in AC and DC environments, and can be applied to power grid environments with larger distributed capacitance. It can completely replace foreign brands.
