Description
Technical field
The utility model relates to a kind of two period cable circulating-heating test units, cable is done to accelerated aging test for the different periods, belongs to the technical field of performance test of electric wire.
Background technology
Along with the development of national economy, electrified, robotization prosperity day by day.Various special electricity consumptions require constantly to propose, and this not only has higher requirement to the generation quantity of electric wire, and have also proposed diversified requirement in performance, serviceable life to electric wire.
In order further to popularize and improve production and the operation level of electric wire, ensure product quality, ensure the safe operation of electrical network, meet the requirement of the more Gao Gengxin of economic development to electric wire proposition, it is the detection that R&D institution or manufacturer all need electric wire to carry out performance, find in time defect, further reduce economic loss.
Traditional durability test for electric wire need to consume a large amount of time, and general 1 group of test need to be done 8 hours, stops 16 hours, then carries out lower battery of tests.Huge due to test quantity, and the raising of testing cost, is necessary to develop a kind of device of accelerated aging test, such device yet there are no open report in the prior art.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of device that cable is carried out to accelerated deterioration experiment.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of two period cable circulating-heating test unit, it is characterized in that: comprise PLC control module, PLC control module connects induction voltage regulator, first group of loaded cable connects induction voltage regulator by the first transformer, and second group of loaded cable connects induction voltage regulator by the second transformer.
Preferably, described induction voltage regulator is connected with 380V AC power, and first group of loaded cable is all connected with sensor with second group of loaded cable, and sensor connects PLC control module by analog input/output module; Described induction voltage regulator connects wave filter, probe power input end and PLC control module power input by MDQ, and wave filter connects PLC control module.
Preferably, described the first transformer, the second transformer are open-type punching transformer.
Two period cable circulating-heating test units that the utility model provides carry out two periods switchings by PLC control module, the 1st period carried out the test of first group of loaded cable, the 2nd period carried out the test of second group of loaded cable, originally 1 group of test is to do 8 hours, stop 16 hours, switch and can carry out 2 groups of tests by two periods now, equal to have saved 8 hours.A set of PLC control module and 2 groups of testing transformers of a set of pressure regulator control for this device, drive 2 groups of test product loaded cables simultaneously, and point 2 periods test, and have saved occupation of land space, also saves and economized experimentation cost.
The device that the utility model provides has overcome the deficiencies in the prior art, carry out two periods switchings by PLC control module, can within two periods, carry out circulating-heating test to different cables, not only greatly improved test efficiency, and saved occupation of land space, reduce experimentation cost.
Brief description of the drawings
The structured flowchart of two period cable circulating-heating test units that Fig. 1 provides for the utility model;
Two period cable circulating-heating test unit application schematic diagram that Fig. 2 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The structured flowchart of two period cable circulating-heating test units that Fig. 1 provides for the utility model, described two period cable circulating-heating test units comprise PLC control module, PLC control module connects induction voltage regulator, induction voltage regulator connects two groups of cables by two open-type punching transformers respectively, first group of loaded cable connects induction voltage regulator by the first open-type punching transformer, and second group of loaded cable connects induction voltage regulator by the second open-type punching transformer.
In conjunction with Fig. 2, when use, 380V AC power is connected with induction voltage regulator, induction voltage regulator connects wave filter, probe power input end and PLC control module power input by MDQ, wave filter connects PLC control module, induction voltage regulator is providing the variable AC-input voltage to ratings from 20V to open-type punching transformer, has starting potential output, electronic control, the function such as spacing, take-off potential startup up and down.Open-type punching transformer as main frame, produces the required large electric current of test by it in this device.Consider to facilitate the installation of test product loaded cable, transformer core is designed to openable structure.Two groups of loaded cables are all connected with sensor, sensor connects PLC control module by analog input/output module, sensor detects electric current, core temperature and the environment temperature of loaded cable, by analog input/output module, analog signals is converted to digital quantity signal, and is transferred to PLC control module.PLC control module connects industrial computer by 485/232 converter.
In the present embodiment, PLC control module is selected Siemens S7-200-CPU226 type, and MDQ is selected DQZ-220D35F type, and analog input/output module is selected Siemens EM235 type.
Two period cable circulating-heating test units that the utility model provides carry out two periods switchings by PLC control module, the 1st period carried out the test of first group of loaded cable, the 2nd period carried out the test of second group of loaded cable, originally 1 group of test is to do 8 hours, stop 16 hours, switch and can carry out 2 groups of tests by two periods now, equal to have saved 8 hours.A set of PLC control module and 2 groups of testing transformers of a set of pressure regulator control for this device, drive 2 groups of test product loaded cables simultaneously, and point 2 periods test, and have saved occupation of land space, also saves and economized experimentation cost.
