In one embodiment, as shown in fig. 1, there is provided a switch analog control device, comprising an analog action circuit 10 (not shown in fig. 1) and an analog representation circuit 20 (not shown in fig. 1); the analog operation circuit 10 includes a first changeover switch 110;
the first transfer switch 110 includes a first stationary contact 111, a first positioning movable contact 113, and a first unseated movable contact 115; the first stationary contact 111 is used for connecting a first alternating current power supply; the first positioning movable contact 113 is used for connecting the positioning movable terminal 30 of the switch machine; the first flip movable contact 115 is used for connecting a flip action terminal 40 of the switch machine;
the analog representation circuit comprises a positioning representation detection circuit 201, a flip representation detection circuit 203 and a second change-over switch 205; the second transfer switch 205 includes a second stationary contact 210, a second positioning movable contact 220, and a second flip movable contact 230; the second stationary contact 210 is used for connecting a second alternating current power supply; the second positioning movable contact 220 is connected with the positioning indication terminal 50 of the switch machine through the positioning indication detection circuit 201; the second toggle movable contact 230 is connected to the toggle presentation terminal 60 of the switch machine through the toggle presentation detection circuit 203. The change-over switch is a low-voltage switch for switching multiple loops. A plurality of moving contacts are welded on the shaft in an overlapping mode, and when the shaft rotates, the moving contacts are sequentially connected with or disconnected from the fixed contacts, and a circuit is switched. The circuit is changed from one set of connections to another set of connected appliances.
The analog action circuit is used for simulating the circuit state of the switch machine during positioning operation. The analog representation circuit is used for simulating and representing the process that the power supply is changed into direct current after passing through the rectifier diode. The positioning action terminal is a terminal which is connected when the switch machine performs positioning operation. The reversal action terminal is a terminal which is used for switching on the switch machine when the switch machine performs reversal operation. It should be noted that there may be some terminal in common for the positioning action terminal and the range action terminal, depending on the type of switch machine. The positioning indication detection circuit is used for detecting the direction of the indication diode in the indication circuit of the switch machine. The positioning indication terminal is a terminal which indicates a circuit when the switch is in a positioning state. The flip indicates that the terminal is a switch in a flip state and indicates a terminal of the circuit. The positioning indication detection circuit and the flip indication detection circuit are used for detecting the orientation of the diodes representing the electric circuit in the switch machine.
It should be explained that the common position of the switch is the location, and the less common position is the reverse position. Generally, the straight strand is set as the orientation, and the curved strand is set as the inversion. The positioning operation refers to the switch machine switching the turnout to the positioning (straight strand), and the reverse operation refers to the switch machine switching the turnout to the reverse (curved strand).
Specifically, when the flip operation needs to be simulated, the first change-over switch is pulled so that the first stationary contact is conducted with the first flip movable contact, that is, the connection between the first alternating current power supply and the flip operation terminal is conducted. The motor in the point switch is reversed, and the power supply can be automatically cut off after the turnout is reversed, so that the turnout stops working; specifically, turning to the reverse position is that the internal nodes of the switch are disconnected. At this time, if the switch is in the reverse state, the motor does not operate because the internal node of the switch is not closed. After the switch machine is operated, the change-over switch is switched to the middle position, and then the first alternating current power supply can be cut off. When the positioning operation of the switch machine needs to be simulated, the first change-over switch is pulled so as to enable the first static contact to be conducted with the first positioning movable contact, namely the connection between the first alternating current power supply and the positioning action terminal is conducted, and at the moment, if the switch machine is in a positioning state, the motor does not act due to the fact that the internal nodes of the switch machine are different. If the point switch is in a reverse state, the motor rotates forwards, and after the turnout is positioned, the rib node in the point switch is disconnected and the first alternating current power supply is cut off.
Furthermore, when the switch machine is positioned through the analog action circuit, the connection between the switch machine and the first alternating current power supply is disconnected. The second transfer switch is pulled to make the second stationary contact and the positioning indication terminal conducted. Positioning means that the detection circuit detects the direction of the diodes in the switch machine.
And when the switch machine is in the reverse state, the connection between the switch machine and the first alternating current power supply is disconnected. The second transfer switch is pulled to make the second stationary contact and the inversion indicating terminal conduct. The flip bit indicates the direction in which the detection circuit is detecting the diode in the switch machine.
Above-mentioned switch analog control equipment has simulation action circuit and simulation and shows the circuit, can realize carrying out alone analog operation to switch equipment, need not to insert the location, the counterpoint and corresponding instruction function of the verification goat that control system just can be accurate with the switch, can let the operation personnel accomplish the goat construction rapidly in shorter time, debugging, experimental work, reduce simultaneously because the not unblocked condition of indoor outer contact, further provide the efficiency of construction. In addition, the turnout analog control equipment simplifies the turnout outdoor circuit test flow, and saves the cost compared with the traditional analog control equipment. The circuit is converted from parallel connection to series connection, so that the technical threshold is effectively reduced, and more personnel can handle the circuit fault. Because the device can be used for carrying out a relatively thorough test on the outdoor part of the three-phase alternating current point switch before the construction key points, the workload in the skylight point is reduced, the labor intensity in the skylight point is reduced, and the requirement on the construction safety of the turnout is more easily met.
