As can be seen from the figure, the method uses a bridge arm, which is composed of two branches, and is connected to the first end of the secondary side of the first output transformer ρτ_ι and the second output facer ρτ_2 Between the first ends of the sides, ... each of the roads is connected in series with two cold cathode gambling tubes and a stable capacitor c. At the same time, a current balancing transformer Τ-丨 is connected in series between the younger bridge arm and the first end of the secondary side of the first output transformer (5). - / 1 seventh map 'The six cold cathode lamps are connected in series and parallel, and the double output transformer is not intended. As can be seen from the figure, the method uses an arm and a second _, and the first bridge arm is composed of three branches, and is connected to the first end of the correcting wheel_purchasing side - 2 the first end of the secondary side η and - stability secret _, in the branch road to increase the cold cathode lamp is between the 4 brothers and a bridge arm and the first output transformer p and the side of the first end Connect two current balancing transformers T and T-2 in series. From the above-mentioned Fangcun, this is the turn of each bridge, and each branch can be smashed with η paste wood, the main arm of each job is only a cold cathode lamp, the wire arms are bridged, but The number of touch-to-machine contacts depends on the output power of the phase load mode. The number of passes of the hybrid single-arm bridge transformer and the number of lamps of the cold cathode lamp must be balanced according to the output current. The bridge can be connected and connected, and the required amount on the road is less. Achieve an average of several branches of the cold -15- 1282709 cathode lamp inspection. The number of private cold cathode lamps of the slanting balance is L) and the number is β, (1) when the single-arm bridge type is connected with a plurality of cold and fine green branches, as in the embodiment of the seventh figure, the required electricity balance The number of _τ_χ is finally 丨) The number of cold cathode lamps of a music current is regarded as the domain 2. For example, the sixth_example 'four lamps (four), (four) string parallel connection, only need one current balance transformer = (2) two-arm bridged multiple cold cathode tube branches are connected, as shown in the third to fifth figures The actual _, the required current balance surface Kay - the number of lions + the number of cold cathode tubes flowing, this material is positive. For example, in the fourth embodiment of the bicycle, eight cold-rolled lamps (four) and (four) strings are connected in parallel, and only two current-balanced voltage-changing 哭-1, Τ-2 are required. The cold cathode lamp abnormality detecting method of the present invention is applied to the current balance transformer, and the Weiyi detects the coil windings, as the average state of the currents of the respective cold cathode lamps is detected as shown in the following paragraph a). The detection line _ on the current balance transformer τ+τ_2 is Κ-卜Κ-2. If there is an abnormal phenomenon in the electro-hydraulic flow of the cold-cathode lamp on a certain branch of a bridge arm, it is detected that the coil can be immediately sensed by the word (4), and the D-(10) and -_ safety_ The electric job is sent to a ton of control circuit 82 to protect the system, as shown in Figure 8(e). The working principle of the current balance transformer is as follows: taking the first figure (4) to the eighth figure (6) as an example, the number of winding coils N1=N2, taking the first current balance transformer T-i as an example, when the two branches of the M belong When the lamp current of the lamp (10) L-mCCFL-4) on the road is in equilibrium, if there is a slight change in the current of a lamp in M3" complex-16-1282709, the transformer τ-i will be automatically adjusted according to Ampere's law. That is, 'make the trace change close to zero, and make each tube reach equilibrium. (4) Figure 8 (C) 'It is a series of eight cold cathode lamps connected in series and parallel, and the double output is changed to two's method. Schematic diagram of the different f detection method, which includes a plurality of techniques attached to the current balance thinning-η, a plurality of detections - (10), = several, connected ~ Ρ η, _ system security identification _, and - back The control electric power 82. The younger eight _ shows the current balance varnish-1 with the sound map of the detected winding Κ-1, and the eighth figure (6) is the practical figure of the eighth figure (4). Interest: Check the age of the coil on the line according to the demand for the detection signal. Although the brother-current balance transformer Η belongs to the two roads Tube (muscle ^ to the flat weaving,, ❻, W and 职 on the fine branch road (four) - the lamp is often mixed, for example, the lamp aging problem occurs] (four), detect the W on the winding κ_2. And other current balancing transformers τ_η also have the above--if Τ-1 (4)-the tube is in the target of the target. For example, ', in the form of evil, the detection voltage (four) will be sent to the eighth figure C) Checking the mm end of the 'detector μ's wheel will pass through the connection, on the one hand, the drive ιη indicates that the lamp on the branch has an abnormal tube position for generalization), and the 咖 咖 ^ ^ ^: S1 to determine acrobatics (4) Observing the circuit to determine whether the secret should be stopped. In the above, the method of the present invention can effectively reduce the number of required current balances -17-1282709. It can achieve the goal of averaging all kinds of cold and negative currents, effectively improving the know-how of the know-how, and arranging the purpose of the production of the clock value, the entrance to the city. For the sake of all kinds of modifications, it is not necessary to protect the person who wants to protect the scope of the patent application.
