ンセルしあい、巻線内部の電圧はどこでも零となろう。EXAMPLES The principle of the present invention will be described before describing examples. Generally, when the load is short-circuited as described above, the output terminal voltage instantaneously drops to zero (ground potential). At this time, the voltage sharing of each stage largely deviates from the normal operation until then, and the spark gap for protecting the secondary winding of the stage in which the overvoltage occurs is operated. As a result, the voltage across the secondary winding becomes zero, which can be regarded as the normal voltage up to that point plus an impulse voltage of a magnitude that cancels it. The former (normal voltage) is a secondary electromotive force of the same magnitude for each turn of the secondary winding, and has a substantially uniform voltage distribution between both terminals of the winding. On the other hand, the latter (impulse voltage) is a surge voltage that enters the inside of the winding over time. Assuming that this can be made a uniform distribution inside the winding, it will cancel the former (normal voltage) distribution almost, and the voltage inside the winding will be zero everywhere.

に、通常電圧の分布と合成した実際の電圧の初期分布は
どこでも零となり、きわめて好ましいことである。Therefore, hereinafter, only the voltage distribution due to the impulse voltage application will be considered. In particular, the voltage distribution at the moment of applying the impulse voltage is important. This is the initial value of the transient phenomenon. If this is a uniform distribution, as described above, the initial distribution of the actual voltage combined with the distribution of the normal voltage will be zero everywhere, which is extremely preferable.

電流を無視して考えることができる。巻線１ターン毎に
絶縁されているものとみなし、各ターン間の静電容量に
よるネットワーク（網目回路）電圧分担が決まる。The voltage distribution at the instant of impulse application can be considered by ignoring the current in the winding. It is considered that the winding is insulated for each turn, and the voltage share of the network (mesh circuit) is determined by the capacitance between the turns.

として回路方程式をたてればよい。The reason why the current may be ignored is that, when the initial value is considered, the integral value of the current i flowing along the winding is zero at the elapse of time 0 (t = 0). in this case,
The voltage distribution is determined in the network by the capacitance between each turn. The node of the network is a conductor of each turn, and its electric charge (sum of electric charges of the connecting capacitors) may be zero to form a circuit equation.

で、下記の数式１に示した方程式が得られる。For example, it is assumed that an equivalent circuit of a winding is represented by a network of electrostatic capacitance between each turn conductor and the surrounding ground and an inductance along the winding as shown in FIG. Note that this circuit is a model of a single-turn solenoid, and the initial voltage distribution is shown in FIG. By setting the sum of the charges of the three capacitors connected to the point P in FIG. 2 to zero, the equation shown in the following formula 1 can be obtained.

Further, v is represented by the following mathematical formula 2.

It is shown that the voltage gradient is large near 0 and the voltage between the windings becomes excessive. This is an extremely simple model, but since the actual secondary winding is a multi-layer winding, the circuit is more complicated than that of FIG. In the present invention, the capacitance network in this case is considered, and a shape having an appropriate initial distribution is devised.

ため鉄芯直径より十分に大きくしているためである。Referring to FIG. 4, a coil 10 constituting a secondary winding according to the present invention is wound around each phase iron core leg of a transformer, and its inner diameter L1 is defined by the outer diameter of the iron core. Larger by at least 50 mm or more, which ensures high-voltage insulation. Since the coil 10 is separated from the surface of the iron core, the shape of the coil itself is fixed by a method such as vacuum impregnation of epoxy resin. This coil 10 also has a multilayer winding structure in which concentric cylindrical layers are stacked from the inside to the outside, each layer is a solenoid winding, and the winding ends at one end and the beginning of the next layer starts. Leads to. The axial length T1 of the coil and the total laminated thickness (radial thickness) T2 of the coil are both flat parts which are only a few fractions of the inner diameter of the coil. This is because the coil inner diameter is made sufficiently larger than the iron core diameter to ensure insulation.

からである。Referring to FIG. 5, the secondary winding according to the present invention is provided with first and second metal cylinders 11 and 12 which are in close contact with the inner diameter surface and the outer diameter surface of the coil 10. These are respectively connected to the beginning and end of winding of the coil. The first and second cylinders 11 and 12 must also be cut open along the axial direction at one location of the cylinder. This is because the first and second cylinders 11 and 12 are concentric circles with the coil, so that if a closed loop is used, current will flow there.

The length of the extended portion is preferably not less than the thickness T2 in the radial direction of the coil 10 both above and below, but may be less than this if there are dimensional restrictions.

流が流れる。If it is difficult to provide the first and second cylinders 11 and 12 in close contact with the inner diameter surface and the outer diameter surface of the coil 10, a clearance of several millimeters or less is provided between them. Alternatively, a thin metal foil may be adhered to the inner diameter surface and outer diameter surface of the coil 10 so as to be in close contact with each other. These metal foils are connected to the beginning or end of winding of the coil. Of course, these metal foils must also be cut open at one place on the circumference. Further, the metal foil closely attached to the inner diameter surface or the outer diameter surface of the coil 10 may have one end connected to the start or end of winding of the coil and the other end connected to the external wiring. In this case, a current flows through the metal foil as a part of the wiring.

０の内部で電圧集中は起こらない。The function of the secondary winding configured as described above is as follows. The cross section of the coil 10 having the shape shown in FIG.
As shown in FIG. 6, a network of capacitances formed between the windings is formed. The initial voltage distribution in which a surge voltage is applied to both ends of the coil 10 must be taken into consideration even the capacitance between each turn wire of the coil and the surrounding electrodes and structural members. To facilitate this, FIG. 5 shows the first and second cylinders 11 and 12 provided in close contact with the inner diameter surface and the outer diameter surface of the coil 10. First and second cylinders 11, 1
When a pulse voltage is applied to 2 (that is, both ends of the coil), concentric cylindrical equipotential surfaces are formed near the coil at substantially equal intervals regardless of the presence or absence of the coil 10.
No voltage concentration occurs inside 0.

る。Here, if one of the cylinders is not in close contact with the coil 10, the electrostatic capacity in this clearance becomes small and the voltage difference becomes large here, as shown in FIG.
However, since the end of the winding has the same potential as the cylinder, voltage concentration occurs around this end. This state is shown in FIG. The network of capacitance inside the coil is considered as one dielectric as a whole, and its permittivity can be distributed between the metal conductor and the dielectric. Considering the voltage distribution on the line AA ′ in FIG. 8, the inside of the coil has a much higher dielectric constant than the clearance portion, so most of the voltage is borne by the clearance.

い。On the other hand, the end portion on the line BB 'is the second portion on the right side.
Since it is connected to the second cylinder 12, only this end has the same potential as that of the second cylinder 12, and the potential gradient becomes large around this end. For this reason, the first and second cylinders 11 and 12 must be in close contact with the inner diameter surface or the outer diameter surface of the coil 10. If clearance is required for assembly, the metal foil may be attached to the inner diameter surface and the outer diameter surface as described above.
