- Q: I know the switch is called "master electrical" What is the kind of relay and contactor? "Switching element"?
- Buttons, knobs, universal switch, combination switch, inverted switch, etc. is the main electrical appliances; Circuit breakers, disconnectors, load switches, dual power switch, etc. are not the main electrical appliances. The contactor is the contactor class; The relay is the relay class.
- Q: Human body infrared sensor module to connect the electrical method
- First determine your 3v relay coil operating current is how much, if not found, you can use a regulated power supply to 3V string into the multimeter (current) access to the relay to pull, write down the current value, if it is 0.1 A, as the downstairs hby8401 said, we have to calculate the current limiting resistor = (9-3) /0.1 = 60 ohms, its power 0.1 * 6 = 0.6W, select at least 1W above 60 ohm resistance access board 1 foot To the top of the relay (diode negative in the figure), and the transistor emitter connected to 3. The base of the limited current resistance directly into the 2 feet bar.
- Q: Electrician TBJV represents what relay
- This is used to control the relay in the control circuit in the high-voltage circuit breaker, which represents the anti-trip relay, because when the high-voltage switch, if the line is faulty (if the line has a short circuit), will protect the action trip, but As the switch signal is still not open, the circuit breaker will re-closing phenomenon, so the actual circuit will increase a anti-jump relay, when the switch after the first closing switch protection trip, this relay will be locked Close the circuit so that it can not be closed again
- Q: Why solid state relays are solid
- You know the electromagnetic relay has a contact, the coil is energized after the contact action to make the circuit connected, so it is operating state, and solid-state circuit breaker is no contact, the use of thyristor as a switch, when the control voltage signal On the conduction, and no contact action, which has a relay function, not a relay, so give it a solid circuit breaker name, and electromagnetic relays to be distinguished.
- Q: Ordinary relay through the control coil control, how solid-state relay control? , Please explain in detail
- Simple metaphor you today to find the governor, do not know so much official, but you know the mayor, the mayor and then please the mayor, and finally to the governor of the old man hands to you. Similarly control the first control of small light lotus root, small light lotus and then control the big SCR.
- Q: What is the difference between the time relay TIM 0 30 and TIM 0 # 30? Thank you
- # After the number that the time parameter, # 0030, said the set time is 3 seconds
- Q: The work of the car relay, such as five-pin relay they are what the role of each line of the details of the details of the more detailed the more grateful
- 85 and 86 are coils, then positive and negative! 30 and 87a is a closed point, the relay is not energized when the two corners are connected, power off after! 30 and 87 are often open, the principle and 87a the opposite!
- Q: AH3-3 time relay has been known that his coil is seventy-two, often open is four and five eight, normally closed one three and sixty-eight, but do not understand how to start his own power supply, and when he went to time After how their own power, I want him to work in detail, self-study, I hope you prawn educated, grateful
- Time relay can be divided into power delay type and power delay type two types. Air damping type time relay delay range (0.4 ~ 60s and 0.4 ~ 180s two), it is simple structure, but the accuracy is low. When the coil is energized, the armature and the pallet are attracted by the core and instantaneously move down to turn on or off the instantaneous action contact. But the piston rod and lever can not fall along with the armature at the same time, because the upper end of the piston rod attached to the rubber chamber in the chamber, when the piston rod in the release of the spring under the action of downward movement, the rubber film with the concave, The air in the air chamber becomes thin and the piston rod is damped and slowly descends. After a certain period of time, the piston rod down to a certain position, then through the lever to promote the delay contact action, so that moving off the contact open, moving contact closure. From the coil power to the delay contact to complete the action, this time is the relay delay time. The length of the delay time can be adjusted by changing the size of the air chamber inlet with screws. After the suction coil is powered off, the relay relies on the effect of the recovery spring. The air is quickly discharged through the pores.
- Q: Forward, the hair, three friends which relay is good
- I personally used the yuan is the relay products, both in the service or products, in terms of cost-effective advantages. Their positioning mode is better, mainly to do small appliances category!
- Q: What is the use of elevator phase sequence relays?
- The use of elevator phase sequence relays are: 1, phase sequence protection, to prevent the elevator to enhance the direction of motor running contrary to the expected, for example: is expected to ladder downstream, phase sequence error in the case of the actual uplink, in the absence of other measures to install the case, 2, phase protection, to prevent the elevator to enhance the motor in the course of running, suffered a power failure phase failure, resulting in damage to the motor or cause other accidents; 3, overvoltage, undervoltage protection, to prevent the voltage is too high, too low damage to lift the elevator and cause other accidents. The above phase sequence relay in the elevator in a number of protective effects, including phase sequence protection, also known as reverse phase protection, fault protection, etc., generally in the external power supply repair, phase sequence error caused by the situation. Such as the main transformer, after the end of the cable is reversed, etc .; this error, such as elevators, air compressors, central air conditioning and other end users before the electricity is unpredictable, so in this type of equipment installed phase sequence relay Is very necessary, can effectively prevent the corresponding failure of the equipment and other damage. We are in such occasions, long-term use is ZHRV2 series, stable and reliable operation.
