When an electrical circuit or communication line because of external interference suddenly produces peak current or voltage surge protector can in a very short period of time via streaming and thus avoid the surge on the circuit of other equipment. Motor Protector's role is to motor complete protection, over-current, appears in the motor under flow, phase, stalling, short circuit, overvoltage, undervoltage, leakage, and unbalanced state be protective measures, the activation delay, digital ammeter, voltmeter, reveals A, B, C three-phase current, achieving multiple parameter setting function, fault memory warning query and action values hold function, call the auto-start and auto-reset functionality. Surge protectors (Surge protection Device) is an electronic device lightning protection in one device, used to be known as the "lightning" or "protector" of the English abbreviation for the SPD. Leakage protector: now the universalization of pure water machine has begun, but the pure water machine user's floor decoration materials and more upscale, machine leaking brought inconvenience and loss. Leakage protection came into being. Thermal relay is two pieces of different alloys, through current will generate heat, because two different thermal expansion coefficient of alloy, alloys is bound to a direction of bending, shock from electric, was broken. Bending speed and through proportional to the size of the current. This protects the electrical equipment. Motor protector: is the motor for comprehensive protection, over-current, appears in the motor under flow, phase, stalling, short circuit, overvoltage, undervoltage, leakage, and unbalanced state be protective measures, the activation delay, digital ammeter, voltmeter, reveals A, B, C three-phase current, achieving multiple parameter setting function, fault memory warning query and action values hold function, call the auto-start and auto-reset functionality. Hard disk protection card is also called restore card, its main function is to restore the data on your hard disk. Every time when powered on, the hard drive protection card always make part or all of the hard disk partitions to restore the previous content. In other words, any hard disk protected sections of the modifications are invalid, this will serve to protect the contents of the data on the hard drive. Monitoring system lightning protector is divided into: the power surge protector, signal SPD. Overvoltage protective device, also known as "overvoltage protectors, three-phase combination overvoltage protective device, also called the" three-phase combination arrester ". Ball bearing protector by sensing devices and electric controller (protector ontology). Residual current operated protective devices: the provisions of the conditions, when the residual current reaches or exceeds a given value, automatically disconnect the circuit of mechanical switches or combinations. 360 hours protector protects the system time will not be tampered with by malicious software, you can avoid the Kaspersky and some security software failure, some winXP system date tampering as 2000 years ago and cannot enter, charges software failure, QQ unable to login, the Forum could not post messages. Class surge protector: due to the special design can withstand lightning energy and free some direct lightning currents of surge protectors. Residual current protection: low-voltage power grid installation residual current operated protective devices (hereinafter referred to as residual current protector) is to avoid electrical shock, electric fire and electrical equipment damaged an effective protective measures. World countries and the International Electrotechnical Commission through the development of appropriate regulations for the electrical installations and electrical specification for low voltage power network to promote the use of residual current operated protective devices. Power capacitor protector is available and switching capacitor contactors, reactive power compensation controller, fuse, power capacitor control system, mainly as a power capacitors and compensation compensation circuit overcurrent, short circuit occurs, inrush current, Harmonic, over-voltage failure protection, power capacitor Protector for overcurrent protection of new products, filling the domestic power capacitor protector, blank, can be widely applied to power factor compensation control circuit automatically. Lightning protector and insulator, the wire is parallel, through protector-limiting components, current limiting components drainage draining ball and wire series gap between ball with the aim of achieving lightning. Combined overvoltage protector uses three-phase four-column composite structure, apply to 35kv and below power system, which is limiting the lightning over-voltage and overvoltage of an advanced protection electrical appliances. Mainly used to protect the generators, transformers, switchgear, bus, motor, electrical equipment for insulation against overvoltage damage, it is fast, smooth, residual current-voltage characteristics in a low, stable performance, easy Assembly and maintenance. For phase and phase and over voltage can be up to the effective protection. Electronic residual current protection: zero sequence current transformer secondary circuit and release between access an electronic zoom lines, the transformer secondary circuit output voltage through the electronics amplification and incentive residual current release, called electronic residual current protection, their actions and line voltage. Electromagnetic residual current protection: zero sequence current transformer secondary circuit output voltage without any zoom, direct incentive residual current release, called electromagnetic residual current protection, its action is not related to functional and line voltage. Commonly known as the protector, leakage switch is used in the circuit or electric insulation damage occurs on short-circuit proof of physical shock and electrical fire protection equipment, installed in every household distribution box outlet circuit and the whole floor, total distribution box power, which is dedicated to preventing electrical fires. SPD also known as: lightning arrester, spd, SPD.
