AMWEI PTC Thermistor Over-current Protector |
|
|
Ceramic PTC (positive temperature coefficient) thermistors are used instead of conventional fuses to protect load, such as motors, transformers, or electronic circuit, against overcurrent for circuit protection. PTC thermistor protector not only respond to inadmissibly high currents but also if a preset temperature limit is exceeded. PTC thermistor over-current protector limits the power dissipation of the whole circuit by increasing their resistance and thus reducing the current to a harmless residual value. In contrast to conventional fuses, PTC thermistor resettable fuses do not have to be replaced after elimination of the fault but resume their protective function immediately after a short cooling-down time.
PTC Thermistor Over-current Protector Application
It applies in the over-current overload and short circuit protection of transformers, battery charger, switches, switch power supply, adaptor, meter, instrumentation, apparatus, electronic coils, control panels, air conditioner, automotive electron, etc.
Operating Principle of PTC Thermistor for Overload Over-current Protection
The operating principle is as indicated in the following. When a circuit is in the normal status, the current through PTC is lower than the rated current and PTC thermistor protector is in the normal state with small resistance value, which will not affect the normal operation of the protected circuit. In case of some fault in the circuit and the current is greater than the rated current, the PTC thermistor protector will become hot quickly and present a high resistance state, which sets the circuit relatively "off" to protect the circuit from damage. After the fault is removed, PTC thermistor protector will automatically restore its low resistance state and the circuit will resume normal operation.
Normally, when PTC thermistor is used as an overcurrent protection component, it is preferred to select maximum operating current, maximum operating voltage and proper specifications. Furthermore such factors should be taken into consideration as the dimensions of the components, rated zero-power resistance, operating temperature range, etc. |

VFD-R Double-Stage Vacuum Insulation Oil Regeneration Purifier |
|
|
Application:
VFD-R series is adapt to regenerate and activate the deteriorated transformer oil. It's capable of removing the moisture, gas and mechanical impurities as well as eliminating organic acid, sludges, pitches and dissociated carbon on the deteriorated transformer oil which are difficult to be removed by conventional oil purifier plants. After the treatment, the regenerated insulation oil can meet the required standard and life span of new insulation oil.
Description:
VFD-R regeneration units adopt both physical and chemical methods to purify and regenerate the transformer oil. They can not only regenerate the aging transformer oil, switch oil but remove the acid, suspending materials and contaminates.
VFD-R regeneration units adopt special adsorbent. They can be normally run without switching off the power and changing the oil of transformer.After the treatment, the transformer oil will maintain basic ingredients and anti-oxidation capacity to meet the standard of new transformer oil. Meanwhile, the VFD-R regeneration units can keep the power equipments insulating and safe by comsuming only 90% maintenance cost.
