Abstract
A high precision resistor array voltage signal attenuator can realize the precision rate attenuation of a fast pulse voltage signal and a high amplitude voltage signal. A high voltage arm of the attenuator uses a hollow circular copper sheet as a connection support body, a core element uses a metal non-electrode thin-film resistor, the circular array structure is used to reduce the body capacitance of the high voltage arm, increase the ability of the attenuator to response to the fast signal, and the structure has the effect of sharing the voltage to improve the response and voltage withstanding ability to the fast pulse voltage signal; a low voltage arm of the attenuator uses the structure characteristics of a connecting terminal, one end of a resistor of the lower voltage arm is concentratedly welded on a core line of a Q9 connector, and the other end is welded on a flange of the Q9 connector, thus the stray inductance of the low voltage arm is effectively reduced, and the complete distortionless of the signal on the lower voltage end is ensured.
Description
Affiliated technical field
The utility model belongs to a kind of being used for voltage is fixed the electric resistance array type structure voltage signal attenuator that multiplying power decays, it has high accuracy, fast-response, high withstand voltage characteristic, can be widely used in the accurate multiplying power decay of fast-pulse voltage signal and high amplitude voltage signal.
Background technology
At first, along with the development of Pulse Power Techniques and High Voltage current test measuring technique, they are widely used in fields such as national economy, defence and militaries.In traditional high voltage, large current signal measuring technique, normal voltage divider and the Luo-coil of adopting measured these signals as voltage, current sensor respectively, these transducers technical parameter when dispatching from the factory, as: decay multiplying power, response time, temperature coefficient, the linearity etc. are all definite.More and more higher along with the high-voltage large current test request, voltage, the current class of its generation are also more and more higher; Yet, the measurement of its voltage and current is limited by the transducer of fixed multiplying power to a great extent, therefore the transducer that often needs to customize higher decay multiplying power just can be measured, and is badly in need of a kind of energy and effectively is used in conjunction with the high accuracy attenuator with voltage, the current sensor of existing low range and solves this problem.
Secondly, existing attenuator mostly is adjustable multiplying power low-voltage signal attenuator, and withstand voltage level is low, the response time is long, can produce wave distortion and easily breakdown for the decay of the large voltage signal of transition.Yet some can the corresponding attenuator of paired pulses, and its precision is not high.
Summary of the invention
The utility model has designed a kind of precision resister array voltage signal attenuator.Its feature is: at first, can design the attenuator resistance to realize the decay multiplying power according to application demand, reach the decay requirement to high amplitude voltage signal; Secondly, in order to realize attenuator to the response of fast-pulse signal, the high-voltage arm of attenuator and low-voltage arm are carried out annular array process to reduce its distributed capacitance and stray inductance; Again, design has adopted the array type structure to design high-voltage arm, and this design has played from structure power level and the resistance accuracy that the effect of all pressing and shunting has improved high-voltage arm.
The technical scheme that its technical problem that solves the utility model adopts comprises three aspects: the design of (1) attenuator high-voltage arm.Core parts are selected the electrodeless film resistor of metal, adopt the annular array structure, and connecting supporter is the copper coin sheet of hollow, and every layer along eight film resistors of copper coin sheet outward flange uniform welding successively, and resistance value and the needed number of plies can be selected according to the design needs.(2) design of attenuator low-voltage arm.Some film resistors one end is concentrated be welded on Q9 connector core, the other end welds on the flange that is distributed in the Q9 connector uniformly as low-voltage arm, this design has improved the voltage endurance capability of low-voltage arm on the one hand, and compact conformation can reduce stray inductance on the other hand, makes signal undistorted.(3) design of shielding case.Designed a totally enclosed shielding case, attenuator be placed in one, and with whole shield shell as signal ground.
The beneficial effects of the utility model are: (1) can realize flexible design, reduces Financial cost.Can design according to demand the attenuator resistance to realize the decay multiplying power, alleviate the producer's financial burden; (2) in the measurement of high-voltage high-speed pulse, shielding case can effectively reduce spurious signal to the interference of measured signal, thereby improves signal to noise ratio; (2) this attenuator application scope is wide.Attenuator can be realized the accurate multiplying power decay to fast-pulse voltage signal and high amplitude voltage signal.
