TXHPD Harmonic Protector Introduction

TXHPD Harmonic Protector realize protection of various precision control equipments in harmonic environment, such as computers, PLCs, sensors, wireless devices, CT machines, DCS, etc., so as to avoid harm from harmonics. Voltage Protection Device
The use of the TXHPD Harmonic Protector reduces the equipment failure rate and misoperation of the machine, improves the operating efficiency and service life of the equipment, and fully overcomes the poor power quality caused by high-order harmonics on the user side, resulting in equipment loss and abnormal performance. , causing unnecessary losses.
Harmonic Protector fully complies with IEC61000-4-5 IEC60939-1-1 and other standards.
The ideal power supply should be a stable voltage with a single constant frequency and a specified amplitude. However, with the continuous renewal of various new, high-efficiency, multi-functional electrical equipment, these non-linear electrical devices make the voltage and current waveforms of power grids virtually non-sinusoidal with different degrees of distortion. Non-sinusoidal waves contain higher harmonics that can directly harm user equipment and the human body.
Since electronic computers, microprocessors, and other electronic devices generally have high harmonic quality requirements for power supplies, due to the presence of higher harmonics, programs often appear in these highly sensitive electronic systems. Operational errors, data errors, time errors, crashes, restarts without cause, and even permanent damage to electrical equipment have caused huge losses to people's work and daily life. General equipment works under the condition of “transient” frequency of 200,000 times/hour, the life of electronic equipment will be shortened by 40%, the life of motor equipment will be shortened by 30%, and the life of lighting equipment will be shortened. 35% to 45%. According to statistics, 75% of failures in electronic equipment are caused by transient surges. Basically, whenever an inductive load is cut off, there will be user-side higher harmonic generation many times higher than the peak value of the normal voltage.
TXHPD harmonic protection device is precisely for the user side high harmonic (2KHz-10MHz) pollution, for power equipment to provide harmonic protection, improve the more and more poor power quality equipment. TXHPD The harmonic protector adopts a special circuit of ultra-microcrystalline alloy material and innovation technology, and it suppresses and absorbs real-time harmonics, high-frequency noise, spikes, etc. generated on the user's side of the electrical equipment. Use; to follow the power waveform at any time, instantaneously filter out peaks in the power supply, user-side harmonics, clutter, correct distortion of the power waveform caused by the harmonic effect, digest the noise, improve the power waveform, The grid power waveform becomes light and clean, which improves the quality of the power grid and ensures the normal operation of instruments and equipment.

The main harm of higher harmonics
1. Make the equipment (such as PLC, sound, medical equipment, relay protection, measuring instruments, power electronics, computer systems, precision instruments, etc.) not function properly or operate correctly;
2. Harmonic loss occurs, and the efficiency of using electrical equipment is reduced;
3, accelerate the insulation aging of electrical equipment, making it easy to breakdown, thereby shortening their useful life;
4, cause series resonance and parallel resonance, amplify harmonics, causing dangerous over-voltage or over-current;
5, interfere with the communication system, reduce the signal transmission quality, damage the correct transmission of the signal, and even damage the communication equipment.

The Role of TXHPD Harmonic Wave Protector

TXHPD harmonic protector eliminates the harmonics, reduces the skin effect of the conductor, avoids the temperature rise of the conductor, greatly reduces the copper loss and iron loss of the transformer, and reduces unnecessary Energy consumption. At the same time, the TXHPD Harmonic Protector also eliminates user-side harmonics, spikes, and other noises that are extremely destructive to electrical equipment, so that the current and voltage in each phase circuit tend to balance and the phase difference remains the same. Played a variety of equipment design features to achieve the purpose of not wasting electrical energy.
TXHPD Harmonic Protector adopts high-tech crystal-producing ultra-microcrystalline alloy material, which can reduce user-side high-frequency harmonics and high-frequency noise generated by instruments and equipment, prevent pollution generated by power equipment from entering the power grid, and at the same time prevent High-frequency harmonics in the power grid, and high-frequency noise, user-side harmonics, spike transients, and other pollution entered the equipment and interfered with the operation of the equipment. At 2kHz~10MHz The high-frequency filter absorption effect in the frequency band achieves the effect of improving power quality.
Using TXHPD Harmonic Wave Protector to Solve Many Problems Encountered by the Device

Automatic Protection Devices

Since the ground current generated by the device itself will cause a voltage drop between the device and the real ground, when the noise frequency is relatively high, the kiln-to-noise computer electronic equipment, the PLC, the motor, etc., computer crashes.
TXHPD can automatically eliminate true destructive higher harmonics, high-frequency noise, user-side harmonics, spike transients, etc., to ensure the life of electrical equipment.

Purifying Power Supplies

TXHPD harmonic protection device has a very strong suppression and elimination capability. It can eliminate up to 99% of the voltage and current distortion caused by various harmonics, prevent computer screen strobe caused by harmonics, and switch, short circuit and load. The light flashes caused by the change.

Improving the Harmonic Environment of IT Equipment to Prevent Data Network Blockage

IT equipment is a sophisticated device that is very sensitive to various frequency disturbances and has higher harmonics The voltage distortion will seriously affect the quality of IT equipment and greatly increase the bit error rate of communication lines. It can even be high enough to paralyze the entire network.

Protecting Power Factor Compensation Devices

Higher harmonic frequencies may be combined with spurious grid inductance and power factor compensation (PFC) equipment The harmonic frequency forms a parallel resonant circuit, harmonics caused by the resonant circuit amplify voltage and current waves Deformity is severe, resulting in equipment failure and failure. TXHPD eliminates harmonic pollution Ensures the service life of power factor compensation devices

Preventing protection devices from tripping by mistake

Harmonic currents can cause circuit breakers to trip by mistake or not to jump at all during this trip.
