Abstract
The utility model discloses a novel measuring system for an air reactor thermal resistance, comprising a plurality of measuring channels, a multipath constant current source module, a DSP unit, and a PC machine, each measuring channel is respectively connected with the multipath constant current source module, and the multipath constant current source module is successively connected with the DSP unit and the PC machine via a communication interface. The novel measuring system can realize simultaneous measurement of the multi-encapsulating and multi-layer lead thermal resistance of the air reactor, and is characterized by quick charging, timing, accurate measurement, capability of random increase of the measuring channel number, etc.
Description
Technical field
The utility model relates to a kind of system that the air reactor hot resistance is measured.
Background technology
Recommend the extrapolation method of experiment power supply winding temperature during breaking moment according to GB (GB1094.2-1996) C3 clause, require " in the instant about 20min of rising that cuts off the electricity supply, should obtain a considerable amount of discrete values, as the data of extrapolation dump moment temperature rise.Be extrapolated to dump moment with these discrete values from the time, thereby obtain required (dump moment) value." in reactor test, due to its reasons in structure, need to reach tens during test and seal or the hot resistance measurement of tens layers wire, often to be sealed or the average temperature rising numerical value of every layer conductor.Existing instrument for measuring DC resistance only can provide the test function of maximum 3 passages, can not satisfy testing requirements far away.
Summary of the invention
The problems referred to above that exist for solving existing proving installation, the utility model provides a kind of novel hollow reactor hot resistance measuring system, and its technical scheme of taking is:
This system comprises a plurality of measurement passages, multiple constant current source module, DSP unit and PC, and each is measured passage and connects respectively the multiple constant current source module, and the multiple constant current source module connects DSP unit and PC successively by communication interface.
Measure when the utility model can realize that air reactor is sealed with the multi-layer conductor leads hot resistance more, but have rapid charge, regularly, accurately measure and the characteristics such as test channel quantity arbitrary extension.
Description of drawings
Fig. 1 is system architecture diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, measure passage for n and connect respectively the multiple constant current source module, the multiple constant current source module connects DSP unit and PC successively by communication interface.Each measure passage respectively with reactor respectively seal (or every layer conductor of sealing) as measuring unit, choose the maximum of multiple constant current source module according to practical measurement requirement and measure number of channels.The DSP unit by 485 communications to the multiple constant current source module respectively measure passage size of current, Measuring Time, discharge and recharge the parameters such as time and detect and measurement result is sent to PC, by PC according to receive data each measurement parameter of adjusting, control the switching state of respectively measuring passage, calculate and export measurement result.
