Ammeter 71, voltmeter 72 and each button of stirring electrically connect with the controller；Very first time relay 51 and second
The time relay 52 is separately positioned on two branch roads in loop.
The controller is PLC modules or micro computer.
Five groups are provided with the table top 2 and stirs shelves 9, shelves 9 at least two is stirred for every group and stirs button.Every group is stirred
Shelves 9 are to stir button described in six.Be provided with five ammeters 71 on the panel 3, five ammeters 71 respectively with five groups
Shelves 9 are stirred to electrically connect.
There are five groups of wiring points on the binding post 4, this five groups of wiring points are parallel with one another and connected with the controller.
It is parallel connection that button is stirred described in any two of every group.
As Fig. 2, Fig. 2 show circuit diagram of the present utility model.The utility model is made up of two loops, this two loop difference
For major loop and subloop, major loop is connected by bridge heap 104 with subloop.101 in Fig. 2 switch for electric capacity gear selecting, and 102 are
Electric furnace gear selecting switchs, and 103 be tested NTC, and NTC is thermistor (similarly hereinafter).It can be seen that voltmeter 72 measures main circuit
Voltage, ammeter 71 measure the electric current of branch road where each group stirs shelves.The very first time is respectively arranged with the two poles of the earth of main branch
Relay and second time relay, are additionally provided with miniature circuit breaker 105 in main branch, and the miniature circuit breaker is used as this experiment
The power switch of instrument.Two relays in figure also electrically connect controller, it is illustrated that middle controller is PLC modules.Electric capacity in Fig. 2
The setting of gear selecting switch, is to surge is produced in circuit, produce the surge current of moment, observe the work of NTC under the electric current
Make state.Electric furnace gear selecting steady-state current and electric capacity gear selecting surge current superposition under, line number is entered to thermistor
Secondary Shocks, observe the fine status of resistance.If after being tested under the number and gear of setting, resistance is still intact, illustrates the heat
The performance of quick resistance meets the requirements, if resistance is bad by impact, illustrating the performance of the resistance can not meet the requirements.Understand, this experiment
Instrument is a destructive experimental provision.
Such as Fig. 1, stir shelves for one group and stir button, respectively A shelves, B shelves, C shelves, D shelves, E shelves, F shelves, Mei Yidang including six
Resistance value can according to circumstances set, because voltage constant is 220V, change resistance value namely change power, the present embodiment is adopted
With following setting value, A shelves are 100W, and B shelves are 150W, and C shelves are 200W, and D shelves are 500W, and E shelves are 1000W, and F shelves are 2000W, can
