Judgement, realize safer more efficient test job, concrete scheme is as follows:
A kind of header box integrated testing platform, comprising:
Resistance test circuit, the resistance test circuit include beating pressure-resistant position to header box to provide the voltage resistant instrument of pressure resistance output, with
And for switching the test point conversion equipment for beating pressure-resistant position；
On off test circuit, the on off test circuit include the constant-current source being sequentially connected in series, main contactor, several branch's contactors
With several probes, one end is connected with main contactor after several described branch's contactors are in parallel, the other end and several probes
One end after parallel connection is connected, and the other end after several probes are in parallel is used to connect the fuse of busbar, the main contactor
The other end be connected with the output end of constant-current source；
Controller, the controller are used to receive the test voltage of voltage resistant instrument, and the controller is for controlling test point conversion equipment
Switching, the controller is for controlling main contactor and several branch's contactors.
Further, the test point conversion equipment includes the several groups electromagnet at corresponding several dozen of pressure-resistant positions and micro-
Dynamic switch, the controller can control the corresponding pressure resistance output for beating pressure-resistant position of electromagnetic actuation conducting, the electromagnetic actuation
The normally opened node action of the microswitch of its same group afterwards, and fed back to the controller.
Preferably, it is sequentially connected between the voltage resistant instrument and controller by decompression transmitter and voltage transmitter.
Preferably, the controller is also connected with header box breaker signal test lead and header box Surge Protector signal
Test lead.
From the above technical scheme, the test equipment of dispersion is packed into cabinet by integrated test platform by the present invention
In, so that original manual testing is converted into intelligence test, both improve testing efficiency, in turn avoids the maloperation of people and the visitor of people
It sees and determines result.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of test platform of the present invention.
Specific embodiment
A kind of preferred embodiment of the invention is described in detail with reference to the accompanying drawing.
Header box resistance test predominantly detect positive bus and negative bus-bar over the ground, to zero or positive and negative anodes busbar connector it
Between pressure resistance, pressure-resistant position is beaten to needs and applies experimental voltage (experimental voltage is according to relevant criterion adjustment), former voltage-withstand test is
Man-hour manually hand-held prod point touches pressure-resistant position, and there are poor contact, missing inspection and security risks.It is changed to detect automatically and will change this
A little defects, while controller connects host computer, test action can be shown in host computer, and recordable test process and test knot
Fruit, to the voucher after product number as product quality retrospect.
As shown in Figure 1, the header box integrated testing platform includes resistance test circuit and on off test circuit, difference
The pressure resistance and on-off of header box are detected.
The resistance test circuit includes voltage resistant instrument 1 and test point conversion equipment 2, and wherein voltage resistant instrument is used for header box
Multiple to play pressure-resistant position offer pressure resistance output, the pressure resistance output of voltage resistant instrument passes through decompression transmitter 3, is depressurized to voltage transmitter 4,
Pressure-resistant output signal is fed back to controller 5 by voltage transmitter.
The automatic detection of header box pressure resistance is that test point conversion equipment is controlled by controller, and when test only needs each survey
Pilot connects voltage lead, and presses testing button, and controller automatically controls test point conversion equipment, applies to pressure-resistant position is beaten
Voltage.In the present embodiment, beat pressure-resistant position have positive bus, negative bus-bar, and zero, having for pressure resistance output can be applied
Positive bus-negative bus-bar, positive bus-zero, positive bus-ground, negative bus-bar-zero and negative bus-bar-
Ground, test voltage and testing time can be set, and test voltage is fed back into controller when test, can then sentence when there is voltage downslide
Fixed pressure resistance is unqualified, and warning note, test terminates, and is as a result stored in host computer.
The test point conversion equipment 2 beats pressure-resistant position for switching comprising if corresponding several dozen of pressure-resistant positions
Dry group electromagnet 21 and microswitch 22, the controller can control the corresponding pressure resistance for beating pressure-resistant position of electromagnetic actuation conducting
It exports, the normally opened node action of the microswitch of its same group after the electromagnetic actuation, and is fed back to the controller.Using electromagnetism
Iron acts the principle of contact, and contactor gap is greater than 3000V discharging gap.
Header box on off test is that whether fuse installs fusible core before testing busbar connector, is had between positive bus and fuse
Current transformer gives positive bus to apply electric current when test, while testing whether current transformer is qualified, and negative bus-bar is molten
Disconnected device has only tested whether fusible core, former manual testing there are poor contact, missing inspection, time-consuming the problems such as.
If the on off test circuit include the constant-current source 6 being sequentially connected in series, main contactor 7, several branch's contactors 8 and
Dry probe 9, one end is connected with main contactor after several described branch's contactors are in parallel, and the other end is in parallel with several probes
Rear one end is connected, and the other end after several probes are in parallel is used to connect the fuse of busbar, the main contactor it is another
One end is connected with the output end of constant-current source.
The constant-current source 6 accesses main contactor 7, and the normally opened contact of branch's contactor 8 is connected to probe 9, and probe is inserted into direct current
At header box anode fuse pile crown screw, controller control branch's contactor is successively attracted, to direct current conflux case branch current
It is tested.
Header box on-off detects automatically, is to control one group of contactor by controller, in turn to positive bus and fusing
Device inlet wire applies electric current, while detecting current transformer test electric current, says as mutual inductor output electric current is equal to application test electric current
The success of open-wire line road proper testing, otherwise warning note, manual intervention detection are fuse failure or mulual inductor malfunction, and cathode converges
Stream row and cathode fuse only test whether to be connected, and test terminates, and is as a result stored in host computer.
The controller 5 is used to receive the test voltage of voltage resistant instrument, and the controller is for controlling test point conversion equipment
Switching, the controller is for controlling main contactor and several branch's contactors.The controller is also connected with header box open circuit
Device signal testing end 10 and header box Surge Protector signal testing end 11.
Embodiment described above is only that preferred embodiments of the present invention will be described, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention
The various changes and improvements that case is made, should fall within the scope of protection determined by the claims of the present invention.
