Capacitor

HIEC 311C special filter capacitor is the latest generation of cylindrical low-voltage self-healing capacitor independently developed by Hesreico Electric in order to improve the power factor of the power grid and improve the power quality. Its components are manufactured in an environment close to the 100-level purification level, avoiding oxidation and partial discharge of electrodes. The medium adopts reinforced high-temperature resistant metallized polypropylene film, which makes the dielectric strength and electrical weakness much higher than similar products in the industry. The filler is epoxy resin, compared with other fillers, it has the advantages of good insulation performance, good mechanical performance, and good heat dissipation performance, which ensures safe and reliable operation.

Reactor

When there are a large number of harmonic source devices such as rectifier and converter in the low-voltage power grid, the high-order harmonics produced by them seriously endanger the safe operation of the main transformer and other electrical equipment.

reactive power compensation controller

The HIEC 311 series reactive power compensation controller is a compensation controller with reactive power as a sampling physical quantity. The controller reliably operates in the harsh grid environment such as large harmonics, non-sinusoidal current, strong interference, etc. The advanced and unique adaptive function ensures the safe use of power capacitors, truly realizes the safe use of power capacitors, and effectively improves the power grid Power factor.

intelligent capacitor

Anti-harmonic low-voltage intelligent power capacitor is a common or Y-type low-voltage power capacitor as the main body, using microelectronic hardware and software technology, micro-sensor technology, micro-network technology and electrical manufacturing technology and other latest technological achievements, to achieve intelligent low-voltage reactive power compensation function. It can easily realize a series of functions such as zero-crossing switching, protection, measurement, signal indication, online, etc., which is a major breakthrough in low-voltage reactive power automatic compensation filtering technology. The product is mainly used in reactive power compensation of harmonic occasions, can operate reliably, does not produce resonance, has no amplification effect on harmonics, and has the function of absorbing and eliminating harmonics to a certain extent. Among them, the products connected in series with 7% reactors are used in the electrical environment where the main harmonics are 5th and above, and the products connected in series with 14% reactors are used in the electrical environment where the main harmonics are 3rd.

DVR

HIEC DVR dynamic voltage recovery device is a new type of power electronic equipment developed by Shenzhen HISREC Electric Technology Co., Ltd. (HISREC) using advanced algorithms at home and abroad, which is applied to the control of power grid voltage sag, short-term interruption and temporary rise. When the voltage of the power supply system is normal, the load is powered by the internal thyristor of the device. When the power grid voltage is disturbed, the thyristor is quickly turned off, and the device enters the constant voltage source control mode to continuously supply power to the load. When the system voltage recovers, the device starts to modulate the load-side voltage in accordance with the system-side voltage parameters (frequency and phase angle). The whole process is smooth, without any disturbance to the load, so as to realize the function of dynamic control of voltage sag, short-term interruption and temporary rise of power supply system. In addition, the device also has the functions of dynamic compensation of reactive current and suppression of power harmonics, which can comprehensively manage and improve the power quality of users.

PCD

HIEC PCD is a comprehensive power quality control device, which has the functions of three-phase imbalance compensation, dynamic reactive power compensation and harmonic current compensation, and can solve the power quality problems in the power distribution network in an all-round way. HIEC PCD through real-time monitoring of the load imbalance and compensation, the use of advanced control algorithms to improve the dynamic response speed of imbalance management, three-level NPC power conversion circuit for HIEC PCD to provide more accurate current compensation, all-round improvement of power quality, reduce grid losses, improve the energy efficiency of power supply equipment.
