Description
Technical field
The utility model relates to restriction DC component resistor in a kind of high-voltage test, belongs to the high-voltage test techniques field.
Background technology
Restriction DC component resistor is general in the high-voltage test uses in the connection and disjunction test of high-voltage AC breaker, plays the effect of adjustment, limit assay loop DC component.In known technology, existing restriction DC component resistor uses very inconvenient.Existing restriction DC component resistor mainly is to adopt the tabular resistor disc that the insulation dottle pin is housed each other, is installed on the support bar by the serial or parallel connection mode, and insulator is housed at the support bar two ends and the resistor seat is formed.Because structural design is unreasonable, in actual motion, the resistance value adjustment of resistor is very difficult, and be difficult for adjusting accurately, especially when test was out of order, resistor disc easily caused distortion under the state of heavy current impact, cause the resistor short circuit when serious, even have an accident, have hidden danger.Therefore, need a kind of energy security performance height, can conveniently adjust the restriction DC component resistor of resistance.
The utility model content
The purpose of this utility model just provides, and a kind ofly can conveniently adjust resistance value, have again higher-security can high-voltage test in restriction DC component resistor.
For realizing above purpose, the technical solution of the utility model is:
Restriction DC component resistor in the high-voltage test, it is provided with: resistor porcelain seat, upper junction plate, lower connecting plate, resistor rod, insulation bracing frame, binding post.Resistor rod is installed on the insulation bracing frame, and the requirement of upper junction plate and lower connecting plate current value and resistance value when testing is the resistor rod serial or parallel connection, and is fixed on the resistor rod two ends, and the resistor rod of outer end is separately installed with binding post.
Restriction DC component resistor in the above-mentioned high-voltage test, described resistor rod are the cylindrical resistor rods of being made by austenitic steel or ferritic steel or nichrome aluminum alloy resistance material.
Restriction DC component resistor in the above-mentioned high-voltage test, described resistor rod lower end is provided with the screw thread of trickle adjustment resistance value, and connecting plate is installed in the resistor rod two ends, adjusts the resistance that connecting plate distance up and down can trickle adjustment resistor.
Because such scheme has been adopted in the utility model design, it is unreasonable to have solved existing high voltage resistor structural design effectively, adjusts the resistance value difficulty in the actual motion, has the problem of potential safety hazard.Show through result of the test, it compared with prior art, it is new to have structure, easily adjust, indeformable in the high-voltage large current test, advantage such as stable safe in utilization, be applicable in the connection and disjunction test of high-voltage AC breaker adjustment, limit assay loop DC component.
