A pulling method of a simulation test device of a portable direct current switch machine comprises the following steps:
s1, when the switch is pulled from the location to the reversal, the reversal operation button FCA is pressed, the reversal operation relay FCJ will press the reversal operation button FCA to switch on the power of the reversal operation relay FCJ coil 14, then the reversal operation relay FCJ is excited and sucked up, after the reversal operation relay FCJ is excited and sucked up, the self-closing circuit is switched on through the second group of sucking up contacts of the reversal operation relay FCJ, at this time, the reversal operation is needed to be checked to show that the relay FBJ is in the falling state, the switch relay is not pulled towards the location, at the same time, the switch relay ZHJ is sucked up, after the switch relay ZHJ is sucked up, the self-closing is realized through the cooperation of the third group of contacts and the normally closed contact of the location operation button DCA, the switch relay is the reset relay of the switch relay ZHJF, the switch of the location and the reversal circuit is realized by the large current contact, and the double functions of the switch operation and the representation are realized.
After the switch reverse position control relay FCJ is excited to suck and self-close, the negative polarity direct current 220V power supply rectified by the pulling power supply rectification module 9 is supplied to the pulling control line through the third group of sucking contacts of the reverse position control relay FCJ through the direct current piezoelectric current meter, and meanwhile, the positive polarity power supply rectified by the pulling power supply rectification module is supplied to the pulling common line through the first group of sucking contacts of the reverse position control relay FCJ and the first group of sucking contacts of the switching relay repeating relay ZHJF to represent the pulling common line, so if the internal wiring of the switch is correct, the switch can rotate from the positioning to the reverse position.
When the turnout needs to be pulled to a location, a location operation button (DCA) needs to be pressed, a coil 14 of a location operation relay (DCJ) obtains a power supply to attract the excitation, a second group of attraction contacts of the location operation relay is connected with a self-closing circuit, and the location of the relay DBJ is checked to show that the relay DBJ is in a falling state, so that the turnout can be effectively prevented from being powered to the turnout by mistake when being located.
After the positioning control relay DCJ is excited to suck and self-close, a negative direct current 220V power supply rectified by the pulling power supply rectification module supplies power to a turnout pulling line through a direct current voltage ammeter and a positioning control relay (DC) third group of sucking contacts, and simultaneously, a positive power supply rectified by the pulling power supply rectification module supplies power to a pulling common line through a first group of sucking contacts of the positioning control relay DCJ and a first group of falling contacts of the switching relay repeater ZHJF to indicate that the pulling common line supplies the positive power supply.
After the turnout is switched in place, the pulling power supply is disconnected through the contact of the automatic switch of the point switch of the external test, at the moment, if the contact is good and the contact resistance is in a reasonable range, the corresponding indicating relay is switched on, the indicating relay adopts the working voltage of direct current 110V, the indicating relay obtains the direct current working power supply through the current limiting resistor R and the parallel capacitor, the indicating circuit shows that the polarity of the power supply is consistent with the calibration polarity, the indicating lamp inside the relay is lightened, if the polarity of the power supply is inconsistent with the calibration polarity, the indicating relay is sucked up, the indicating lamp inside is turned off, the indicating circuit state is complete, the polarity of a field diode is reversed, and the point switch is timely searched.
Positioning represents a DBJ excitation circuit of the relay: the positioning indication relay DBJ coil 14 is connected with an indication lamp system circuit positioning indication lamp circuit through a second group of suction contacts 6-10 of the positioning indication relay DBJ to turn on a green light to light through a corresponding loop in communication with the contacts inside the switch machine through a (2-10) of a second group of falling contacts of the switching relay ZHJ → a (1-9) of a first group of falling contacts of the positioning control relay DCJ → a (2-1) of a first group of falling contacts of the switching relay ZHJF → a power supply for pulling a common line to transmit alternating current of 110V, and an external port terminal 3 is connected with an indication line → an indication transformer (lead 2) to exchange the alternating current of 110V.
The inverted position represents the excitation circuit of the relay FBJ: the reverse position indicates that a coil 13 of the relay FBJ turns on a reverse position indicator lamp circuit yellow light through a second group of suction contacts (6-10) of the switching relay ZHJ → a first group of falling contacts (1-9) of the reverse position control relay FCJ → a first group of suction contacts (2-3) of the switching relay ZHJF → a switching common line (X2) for transmitting alternating current 110V power, communicates corresponding loops with the contacts in the switch machine, and is connected with a special line (X3) through an external port terminal 3 for representing the alternating current 110V of the transformer, and simultaneously turns on the reverse position indicator lamp through a second group of suction contacts (6-10) of the reverse position indication relay FBJ.
The invention uses the direct current switch circuit as the blue book, on the premise of not changing the original circuit function, adds the contact resistance detection circuit for realizing the inspection of the internal contact of the motor, when the lead resistance of the automatic switch and each terminal in the switch is too large (more than 100 omega), the detection indicator lamp will turn off the lamp and not turn on the lamp. The input 220V alternating current power supply is converted into a pulling power supply for the turnout switch machine through the rectification module, after the positioning operation button DCA is pressed down and switched on, the positioning operation relay DCJ relay excitation circuit is switched on, the positioning operation relay DCJ relay is sucked up, the motor pulling power supply rectification module is switched on through the third group (11-7) of sucking up contacts of the positioning operation relay DCJ to send direct current pulling power supply for X4, and at the moment, the other pole of power supply is matched with the falling contact of the relay ZHJF through the first group (5-9) of sucking up contacts of the positioning operation relay DCJ to be supplied with power for X1, so that the turnout is converted. When the switch is in the reverse operation, the reverse operation button FCA is only needed to be pressed to connect the reverse operation relay FCJ and the switching relay ZHJ circuit, and the switch is switched to the reverse position by matching the reverse operation relay FCJ and the switching relay ZHJ circuit. When the turnout is in place, the contact of the switching relay ZHJ and the switching relay duplicate relay is used for switching on a corresponding representation relay circuit, the representation relay is sucked up, and corresponding representation is given.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
