How it works and what used voltage relays ?

What is the use?

This protective device is necessary as a circuit breaker.However, this machine a different purpose - to monitor the voltage.

Overvoltage in the common cause of network output expensive equipment out of order, repair and replacement which costs a lot of money, because the breaking overvoltage is not a warranty.And as a rule, such jumps lasts a few seconds, until the substation protection does not work, this will be enough to electronics in the house is out of order.Look how much you have enabled appliances into the outlet, even if they are not using at the moment, they are all potential threats.

To avoid this created tension relay, which the clock monitors the electrical potential in your apartment and instantly de-energize the network in the event of abnormal changes.

Note the single-phase relay RN-104 volt control Novatek Elektro from producer.Easy to set up and use, it will be on guard of the electrical network of your home or apartment.Below we describe the design and operation of voltage control relay.

Features

It is made in the body to mount a DIN rail for installation in accounting guard next to circuit breakers, which can be seen in the photo below.

The front panel has three segment display that shows the current status of the power supply.Three control and three terminals for connection, everything is easy.

On the right side of the hull painted connection diagram 1 Input phase L from the machine 2 from the zero line N tires or from the second machine, depending on your panel, on a zero to this terminal goes on to consumers.With the third phase of the terminal goes to the consumer or a group of machines, again, depends on your guard, you are putting a new or upgrading an old one.For details on how to connect voltage relay to the network, we are told in the corresponding article.

opening the device, we can look closely at the device from which it is composed.Accurate Brazing indicates that the person did not participate in the assembly of electronic components, it is done on an automatic line.human involvement minimized only at the assembly stage in the housing, testing and packaging.

Structurally, the controller is made of two boards, power and control.Almost the entire surface of the power switching circuit takes a powerful relay 40 amps.This makes it easy to include the total load 9 kW, which is enough for houses and apartments.Conclusions from it are welded to the copper leads and output to the screw terminals.

Setting

Manufacturers Novatek-Electro, developing the relay, send people to meet and have programmed in this unit, basic functions, and users have a simple choice from several options, such as:

• the automatic reclosing (APV) 5up to 900 seconds (15 minutes);
• lower threshold cutoff (Umin) 160 - 210 volts;
• upper threshold cutoff (Umax) of 230 - 280 volts.

Turn the potentiometer PH-104 provides an indicator on a digital representation of the parameter, which certainly is convenient and does not need to guess.

We recommend to carry out the setting characteristics of the relay voltage thus:

• reclosure time of 180 seconds;
• Umin 190;
• Umax 245.

In practice, there are moments when the voltage is almost identical to the threshold established for quite a long time and to avoid continuous switching on and off the relay entered the hysteresis 4-5 volts on the set.In this case, the device automatically enters additional threshold and turns on until the voltage drops below the hysteresis value installation.If this phenomenon is cyclical and repeated periodically, revise the parameter settings and change them.

It is worth to say about features volt control RN-104 Novatek Elektro.To avoid nuisance tripping during operation, set intelligent monitoring of the network status.If the voltage is gradually increased, and out of range, but no higher than 30 volts from a set threshold, the relay waits 1 second before switching off.With a sharp jump above the threshold over 60 or higher 285-volt relay is activated immediately for 0.02 seconds.

known that when the powerful consumer undervoltage occurs, they can be a refrigerator or air conditioner.When smooth voltage dips of less than a certain threshold to -60 volts, the device waits for 7-12 seconds, which is enough to start the engine of the consumer. If the voltage drops below 145 V the device operates for 0.12 seconds.

clearly see the principle of voltage relays, you can in the video below:

By the way, the manufacturer guarantees the operating time relay 10years, and guarantee support for 5 years.

Overall, the device looks powerfully and reliably, so when you decide to buy a Volt Control opt described in our paper machine, we reserve about him positive feedback.This concludes our description of the device user, the destination and the RN-104 40 relay action principle voltage A.
