   DZ15LD electronic motor protector broken phase (motor protector) has motor. The leakage, overload, broken phase. Short circuit. Automatic protection. preface According to statistics, every year there are many motors was destroyed, including for broken phase. Short circuit burned down more than 95%. So, to the country and caused a lot of fund waste. Small enterprises and the rural customers are using a knife and thermal relay protection, no reliable protection device. In order to solve the above problem, the company developed protection (such as air pump, oil pump, submersible, machine, such as fans, electric motors) advantages. Whether high pressure cascade fuse drop down, or low voltage insurance and broken, electromotor winding a phase no electricity cause phase lack run reliably protect, break the action time in less than 2 S. In the modern industrial production process. Because of three phase power phase lack, broken by motor is burned up, and become one of the main reasons for the motor destroyed. Especially in some automatic control circuit, a large number of ac contactor, ac contactor use after period of time, contacts and cause damage "phase lack", the motor damage phenomenon of the case. Therefore, three root power phase lack, broken phase that protect a people to study the hot topic of conversation. This company in actual work, according to the work principle of three-phase ac motor, this paper analyzes the main causes damage to the motor development. They set up a what is unique, reliable work convenient installation multifunctional protector. In fault appeared, can cut off power supply in time, realize the protection of the motor. This protector, except for its "ac contactor phase lack" protection functions, but also with good power grid phase lack protection, overload protection, short circuit protection. Is hot relay of the electronic motor protector the renewal of new products. This series product has several models, appear on the market at present integrated motor protector (motor protector, DZ15D molded case circuit breaker), the protector in the can not load condition (motor not connected) can be in action after the break. But the actual fault protection is to point to in all in motor running interrupt phase can protect. No motor running, what is broken phase protection! Once connected motor, power cut in operation of whatever phase, or contactor contact undesirable broken phase, run the motor still broken phase in run to continue. Not a protection. The product model: DZ15LD-40/390 1.5 KW motor protector DZ15LD-40/390 2.2 KW motor phase lack protection circuit breaker DZ15LD-40/390 3 KW motor circuit breaker protection DZ15LD-40/390 4 KW submersible phase lack leakage circuit breakers DZ15LD-40/390 5.5 KW submersible household protector DZ15LD-40/390 7.5 KW submersible professional circuit breaker DZ15LD-7.5 KW motor, 100/390 submersible pump professional circuit breaker DZ15LD-100/390 11 KW motor protector, well pump DZ15LD-100/390 15 KW powerful motor protector A, use DZ15LD-100/3902 electronic motor protector broken phase (DZ15LD circuit breaker, motor protector) is suitable for use in ac frequency 50 HZ, 380 V and rated current to 100 A, power supply neutral grounding circuit, major person get an electric shock, lines of leakage protection with, also can be used to prevent damage to the equipment for insulation, produce ground fault current and cause of the fire, and can be used to protect lines and motor overload or short circuit, three-phase phase lack, also as A line of the start with less frequent. Is the special three-phase motor phase lack leakage circuit breakers. This product USES IEC755-92, IEC947.2 international standards, in line with the GB6829-95, GB14048.2-94 national standards. Second, the structure characteristics This product is our company of autonomous research patent product, the current rapid movement type electronic leakage circuit breakers, mainly by the zero sequence current transformer, leakage tripping device and integrated electronic amplification. Parts. Has the leakage electric shock three-phase phase lack protection function. Three, main technical parameters protection function: Leakage. Overload, broken phase. Phase lack, and phase lack broken phase protection: electric machine Lord circuit in any of the phase without electricity, and, in the action time < 2 S overload protection: motor load current of 1.2 times rated current protection movement response time < 60 S, and it has good inverse time characteristics use environment humidity:-5 ℃ 40 ℃ bastions This product is from Shanghai people's electric Co., LTD.

Clsid = 721    Motor open phase protection switch, air switch) applied to ac 50 hz, rated voltage of 380 v, rated current 250 a circuit, and used as lack of phase, leakage protection, can also be used to prevent due to the damage of equipment insulation, fire danger caused by the grounding fault current. And can be used to protect circuits and motor overload and short circuit, open phase, leak, a line not frequent transformation and also the don't frequent starting of the motor.
