| description | Purpose. Description of construction and basic technical descriptions developed and created in Research & Design Institute «Molniya» National Technical University «Kharkiv Polytechnic Institute» high-voltage heavy-current coaxial disk shunt of type of SC-300M2, allowing reliably to measure the peak-temporal parameters (PTP) of impulses of current of artificial lightning in wide peak and temporal ranges with the integral of their action to 15·106 J/Ohm. Methodology. Electrophysics bases of high-voltage impulsive technique, scientific and technical bases of development and creation of high-voltage heavy-current impulsive electrical equipment, including the powerful generators of current of lightning (GCL), and also measuring methods in bit chains powerful high-voltage GCL AVP large impulsive currents of micro- and millisecond temporal ranges. Results. Offered and described new construction of measuring high-voltage heavy-current shunt, containing a measuring round disk from stainless steel easily soiled a 12Х18Н10Т thickness 2 mm and external diameter 80 mm. Experimental a way impulsive active resistance of RS≈0,08 mOhm of the indicated measuring disk and on his basis a calculation coefficient transformation is found of SS of coaxial disk shunt of type of SC-300M2, numeral equal in the concerted mode of operations of his coaxial cable line (CCL) SS≈2/RS≈25·103 A/V. It is rotined that it is expedient to use this value SS for measuring in the heavy-current bit chain of GCL ATP impulsive A- and repeated impulsive D- component of current of artificial lightning, and also ATP of aperiodic impulse of current of artificial lightning of temporal form 10 μc/350 μc. It is set that taking into account application in the end CCL of shunt of a co-ordinate divizor of voltage with two output coaxial sockets 1:1 (for SSA≈25·103 A/V) and 1:2 (SSC≈12,5·103 A/V) at measuring of ATP intermediate B-, protracted C- and shortened protracted C*- component of current of artificial lightning in GCL it is expedient to utillize a numeral value SS for the examined shunt, equal 12,5·103 A/V. Practical approbation and verification of capacity of the improved measuring coaxial disk shunt of type of SC-300M2 is executed in the high-voltage heavy-current bit chain of powerful GCL, forming on the actively-inductive loading of A- and C*- the components of current of artificial lightning with rationed ATP. Originality. Developed and created new high-voltage heavy-current measuring shunt of type of SC-300M2, allowing reliably to register rationed ATP of attenuation sinewave and aperiodic impulses of current of artificial lightning in the bit chains of powerful GCL with amplitude to ±220 кА and integral them action to 13,5·106 J/Ohm. On the measuring coaxial disk shunt of type of SC-300M2 from government metrology service of Ukraine the certificate of accordance of the set form is got. Practical value. Application of the created shunt of type of SC-300M2 in composition the high-voltage heavy-current bit chains of powerful GCL will allow in a certain measure to improve the metrology providing of tests of aviation and space-rocket technique, and also objects of electroenergy on stability to lightning. |
