Abstract
The invention relates to a novel electric short circuit tester which is used for identifying fire hazard material evidences. The novel electric short circuit tester has the structure that the upper part of a furnace body is provided with a sealed hearth; a motor is arranged below the sealed hearth and is arranged in a cooling box; an output shaft of the motor is connected with the bottom end of a wiring terminal; the bottom of the hearth is provided with a sample catch plate; two electrodes penetrate out of the bottom of the sample catch plate and are respectively positioned on two sides of the wiring terminal; and one end side of the furnace body is provided with a control device. The novel electric short circuit tester has the simple structure, the short circuit condition can be controlled, and the test precision of an identified object is improved.
Description
Technical field
The present invention relates to a kind of novel electric short circuit test instrument, be used for the evaluation of fire material evidence.
Background technology
In recent years, electrical fire played aspect number and the loss total that proportion sharply rises in overall fire, had had a strong impact on social stability and development.Fire identifies scene of fire residue character after taking place in time, exactly, to determining properties of fire, finding out that cause of fire is extremely important.
Fire material evidence identification experiment chamber needs first preparation standard sample usually when identifying scene of a fire residue metal molten character, and the preparation of standard model as far as possible the on-the-spot physical condition of simulated fire could guarantee qualification result accurately with reliably.
Identify the field at the fire material evidence at present, also do not prepare the device of electric short circuit sample, preparation process mainly is to rely on manual operations.The condition when but it can not accurately control short circuit causes different fire material evidence identification experiments chamber different results may occur when preparing identical sample.
Therefore, the fire material evidence is identified and is badly in need of a kind of aut.eq. to satisfy the preparation sample requirement.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of novel electric short circuit test instrument, and this electric short circuit test instrument is not only simple in structure, and can control short circuit condition, has improved the test accuracy of identifying thing.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of novel electric short circuit test instrument, be provided with the burner hearth of sealing on the top of body of heater, its below is provided with motor, motor places in the cooling tank, and the output shaft of motor is connected with the bottom of binding post, is provided with the sample collection dish in the bottom of burner hearth, and passing two electrodes from the sample collection tray bottom, two electrodes lay respectively at the both sides of binding post; A distolateral control device that is provided with at body of heater.
The inwall of described body of heater is provided with heat-insulation layer, and its inside also is provided with heating rod and thermopair.
Gas-filled tube is also inserted in described body of heater outside in body of heater.
The below of described body of heater also is provided with roller.
This electric short circuit test instrument adopts the structure of motor, binding post, electrode and control device, and control device control motor is rotated, and overlaps with electrode thereby drive binding post, is short-circuited, make the sample short circuit after residue fall in the sample collection dish.
Inwall at body of heater is provided with heat-insulation layer, and its inside also is provided with heating rod and thermopair, can make to produce high temperature in the body of heater, thus the hot environment of simulated field.
Gas-filled tube is also inserted in described body of heater outside in body of heater.Can in body of heater, charge into required gas like this, come the simulated field environment.
This electric short circuit test instrument is convenient to be moved in order to make, and the below of described body of heater also is provided with roller.
