Process flow of inductance ballast
(A) the inductance ballast is made up of silicon steel sheet, enamelled wire coil, skeleton end cover, bottom plate (case), terminal and so on. (B) : Coil: generates the induced electromotive force. In current situation, because of the coil has certain resistance, can produce electric power, the heat made the temperature rise of inductance ballast, to speed up the ballast aging. To reduce the resistance in the coils, use high purity imported electrolytic copper wire. Silicon steel sheet, the whole conductor is in changing magnetic field, will cause induced current in the whole piece of internal conductors, commonly called "vortexing", it will cause power consumption and temperature rise. In the inductance ballast, in order to enhance the magnetic induction intensity is core, but due to the presence of eddy current, must use a very thin insulation silicon steel sheet of the overlying formation of the core, with each other instead of the whole piece of iron core, to reduce the eddy current loss. Bottom plate: fixed, installed effect.
Skeleton: fixed coil, chip, convenient connection. Connection terminal: the connection is connected, the inductor is connected to the circuit in series. Is mainly caused by too much load, current big hot wire, construction units should be according to the nominal current of the lamp panel ballast multiplied by 1.6 times between shun starting current for design. Some inexperienced construction units pure designed for surface power, power factor and ignoring the inductor stents only around 0.5 and each ballast about 8 w of their loss. (power for energy saving, compensation is not only to improve the quality of power supply, electricity meter records only active power, no record of reactive power, power factor compensation of single lamp (single) compensation and concentrated compensation in two ways. Compensation is every single light lamps and lanterns is a capacitor in parallel, concentrated compensation in power distribution room to set up an automatic compensation, screen according to the amount of perceptual load in power grid operation, can automatically input capacitance COS phi keep close to the power factor of 1). For example: 40W by 3 lamp plate 10.
Three-phase power supply to balance as far as possible, and each phase voltage cannot be too high, for it is advisable to 220 v, some early engineering (hold) is new factory installation, for installation was not completed, the voltage is too high, may be more than 270 v, the town of inductance ballast may be a slight noise, shall be installed to pay attention to this problem. (2) the installation quality problem: will submit to install according to the installation diagram to install lamps and lanterns of lamps and lanterns, lamps and ballast installed can appear weak noise, lamps and ballasts should not be installed directly on the flammability of body surface and explosive gas, corrosive gas, liquid and dust. Do not use in wet environment.
The line of uncompensated capacitor is designed with the capacity of 20.9 A and above, with compensation capacity of 11.63 A and above. The cause of the leakage switch is: (1) there is too much wire load, too much current causes the tripping, which is based on how much electricity leakage current is used to configure the number of lamps, and the solution: A increases the power factor of the line (plus compensation capacitance) B reduces the number of lamps and lanterns in power lines; C increases the number of ampere (rated working current) of the leakage switch. (2) ballast breakdown or wire breakage caused by contact with the shell of lamps and lanterns of lamps and lanterns leakage protection, this kind of question should be checked according to the actual situation, should be able to find out and replace the ballast or repair damaged wire according to the practical to deal with. The ballast is designed by mute, and if there is noise in actual use
