Circuit: Causes and Solutions to Trips

After the new home is completely renovated, when you check in, all kinds of electrical appliances will follow. Each home decoration will undergo more or less transformation of the original circuit. When the appliances are in place, you may find that when you use electrical appliances The time may be tripping, which causes great trouble. This is the case in my family.

Problem Description

Staying in your new home, please use a group of friends to play. You enthusiastically opened the air conditioner, refrigerator, and stereo in your home. Suddenly all the electrical appliances “strike” and the meter tripped.

problem analysis

Large electric appliances such as refrigerators, microwave ovens, and water heaters have large input power, and they must be routed individually when they are rebuilt, and cannot be shared with other appliances.

Otherwise it is easy to trip and power off when it is turned on at the same time.

Charges to households are overloaded, and the capacity cannot meet the electrical requirements of so many electrical appliances at the same time. This can also lead to tripping accidents.

solution

1. Large-scale electric appliances that use large amounts of electricity should leave power outlets alone. Frequent trips are harmful to televisions, computers, and air-conditioning appliances. Care should be taken to avoid them.

2. After the completion of the circuit construction, a 24-hour full-load operation test shall be performed. All electrical appliances shall be turned on and used after inspection.

3, the kitchen and toilet where water is often used to use waterproof sockets, to avoid short circuit power after pouring water. The kitchen switch is best installed on the open side wall of the room, and the pipeline in the kitchen should be kept away from heat sources such as gas stoves.

4. Frequent power failure requires professionals to check whether the socket is in poor contact or not, and if there is an insufficient capacity in the power box, increase the capacity if necessary.

One of the two causes of tripping is overvoltage. Overvoltage is more than the voltage that the open can withstand, and the second is overcurrent. Overcurrent is over the rated current of open circuit.

Check the line trip First check the line terminal voltage is normal, generally use a multimeter, the line terminal normal voltage between 198V-235.6V, which is what we call 220 volts. If the voltage is too high, be sure to look for the property to check, the power line voltage is too high, which is very dangerous, generally occurs in the "three-phase four-wire" system Power Supply housing. At this time, whether or not the two lines are electrified at the sight of the line; second, whether the neighbors also tripped; and the line voltage with a multimeter. Never close a low-voltage circuit breaker by force. Otherwise, it will lightly burn out electrical appliances, but it will cause fire. If it is too low, it may be a peak of power consumption, resulting in a low terminal voltage. The inspections are divided into three categories: one is open, the other is line, and the third is electrical equipment.

One of the causes of overcurrent is short circuit. Generally, kitchen lines have, fire, zero, ground and three wires. FireWire is very easy to distinguish, using the electric pen can find out, and the zero line and ground, it is not easy to find out, the original I always thought that if the FireWire is right, and the zero line and the ground wire wrong, an electrical It will cause the FireWire to be grounded, and it will be heard directly. This was not the case in consultation. If the live line and the neutral line, as well as the ground line, are directly short-circuited, they will be short-circuited and tripped. If they are powered by electricity, they will be different and can be used. If the fire is connected to the ground, but when electrical leakage occurs, the user's safety cannot be protected because the ground is directly connected to the earth without going through the air. Therefore, it is still recommended to pick up zero and ground. The method is to disconnect the small distribution box ground wire, close the air-open, and see if all the sockets can be used, if there is no use, it means that the ground is reversed.

Poor installation is one of the causes of tripping. Each contact wire is not connected solidly and loosely for a long time, which may cause heat, oxidation, burnout of external insulation of the wire, burning of sparks and burnt smell, resulting in undervoltage of the line, air switch. Trip. Or empty open quality is bad, causing air to open automatically trip. The inspection method is to connect the power-using line to the spare air-opening site and carry out the electricity test to see if it is tripped. If it is skipped, it means the problem of the line and the equipment.

Check the tripping also divided a variety of situations, such as the sub-gate jump, the total gate does not jump, that shows the indoor problem, the total gate jump, the gate does not jump, indicating that the entire electricity line exceeds the total number of currents that the gate can load. Dedicated to a certain electrical equipment to jump, without him, with other not jump, explain the problem of electrical equipment.

In general, although we can determine the cause, we still need an electrician with relevant experience to solve it. Individuals should not change the line automatically to avoid personal danger.
