Abstract
A kind of capacitance current-limiting type impulse power supply that is used for industries such as electric machining.Adopt the electric capacity of two high-frequency high-power pipes and some different capabilities, cancelled Industrial Frequency Transformer and current-limiting resistance and some transistors, working stability is reliable, and is energy-conservation, alleviated the volume and weight of power supply greatly, saved raw material metal and components and parts.
Description
The present invention relates to a kind of pulse power that is applied to industries such as electric machining.
At present, the pulse power that the electric machining industry is adopted all adopts Industrial Frequency Transformer, many transistor parallel operations, uses the resistance current limliting.The fault rate height, volume is big, big energy-consuming, waste components and parts and raw material make the fault rate height of the whole pulse power owing to adopt many transistors, and operating efficiency is influenced, in the transistor circuit of tens parallel connections, if a certain transistor performance instability will influence the power and the performance of the whole pulse power, a wherein a certain transistor damage or puncture will cause the whole pulse power to work; In addition, owing to adopt the resistance current limliting, make that the whole pulse power is bulky, weight is very big, particularly current limitation has very big a part of electric energy reactive power consumption in the course of the work on resistance, and produces the high heat about 70 ℃, and the work of paired pulses power supply produces adverse influence; Have again, adopt Industrial Frequency Transformer that whole pulse power volume, weight are further increased, also wasted various metal materials and components and parts.
The object of the present invention is to provide the high-frequency high-power pipe and the capacitance current-limiting of two parallel connections of a kind of employing, cancellation Industrial Frequency Transformer and current-limiting resistance have improved that existing pulse power volume is big, weight is big, fault rate is high, waste components and parts and raw-material technological deficiency.
Task of the present invention is finished as follows: the electric capacity of 8 different capabilities of the some parallel connections of secondary connection of high frequency transformer and 11 switches, and wherein, four switches and three electric capacity are one group and connect a diode successively, an electric capacity and an electrode tip; In addition four switches and three electric capacity are one group and connect another diode successively, an electric capacity and an electrode tip.Also have three switches and two electric capacity to be one group and connect an other diode successively, the D utmost point of another electric capacity, electrode one end and a high-frequency high-power pipe.And two diode parallel connections connect the D utmost point of another high-frequency high-power pipe by a diode.The S of two high-frequency high-power pipes extremely parallel connection connects the iron inductance and the electrode other end successively, inductance two ends switch in parallel.
Adopt the pulse power provided by the invention, eliminated fault, reduced volume and weight, saved a large amount of components and parts and raw material metal, energy-conservation.
Below in conjunction with accompanying drawing the present invention is done further narration.
With reference to accompanying drawing, diode D1, D2, D3, D4, D5, D6, composition rectification circuit, resistance R 1, R2, R3, K switch 13, capacitor C 1, C2 form current limliting Lu wave circuit, FET BG1, BG2, BG3, BG4 constitute inverter circuit, the elementary end of high frequency transformer B connects the S utmost point of BG1 and the D utmost point of BG2, and the other end connects the S utmost point of BG3 and the D utmost point of BG4.High frequency transformer B secondary has four outputs, export an end and K switch 2 one ends that 1 end connects capacitor C 3, C4, C5 respectively, C3, C4, the C5 other end connect K switch 1, K2, K3 one end, K1, K2, K3, K4 other end parallel connection diode D7 positive pole, the D7 negative pole connects capacitor C 111 1 ends and the positive pole of diode D10 and the negative pole of diode D8, and the negative pole of D10 connects the D utmost point of high-frequency high-power pipe BG5.Export 2 ends and connect the C11 other end, capacitor C 12 1 ends and electrode E end.Export 3 ends and connect capacitor C 6, C7, C8, an end of K switch 8, the other end parallel connection K switch 5 of C6, C7, C8, K6, K7 one end, the positive pole of the other end parallel connection D8 of K5, K6, K7, K8.Export 4 ends and connect capacitor C 9, C10, an end of K switch 11, the other end of C9, C10 connects the end of K switch 9, K10, K9, K10, the other end of K11 connects the positive pole of diode D9, and the negative pole of D9 connects the C12 other end, the D utmost point of high-frequency high-power pipe BG6.The S utmost point of BG6 connects the S utmost point of BG5, the end of iron inductance L, and the other end of L connects the electrode A end, a L two ends K switch 12 in parallel.
BG5; BG6 is according to voltage; the difference of electric current; work alone separately; alternating current AC is through D1; D2; D3; D4; D5; the D6 rectification; R1; K13 and R2; R3; C1; C2 current limliting Lu ripple; again through BG1; BG2; BG3; BG4 is reverse into the alternating current of 20KC; again through the B transformation; as required through capacitor C 3 to C10 current limlitings as if a different capabilities; diode D7 to D10 rectification; offer BG5; BG6 operating current and voltage; iron inductance L and BG5; BG6 operating current and voltage, iron inductance L and BG5; the S utmost point and the electrode A end of BG6 connect guard electrode respectively; with a switch K12 and inductance two ends and connect, the control inductance seals in that circuit carries out work and the short circuit two ends quit work.
