Detailed Description

As shown in fig. 1 to 5, the switching device for the distribution network automation switch set test of the present invention mainly comprises an energy storage power module, a permanent magnet switch module, a transfer switch module, a spring-operated switch module, an AC220V socket 30, an AC220V output 31, and a power supply 32.

The energy storage power supply module comprises a direct current energy storage voltmeter 1, an energy storage input 2, a switching-on public A3, a switching-on input A4, a switching-off input A5, a switching-off public A6, an energy storage output 7, a remote signaling input A8, a remote signaling public A9, a remote signaling input B10, a remote signaling public B11 and an alternating current energy storage voltmeter 12. The energy storage power supply module has no problem in order to detect the energy storage output of the controller. The energy storage motor of a common switch is divided into direct current and alternating current, so that a direct current meter and an alternating current meter are configured, and the alternating current and direct current energy storage voltage can be detected. Fig. 2 includes three major components, namely a direct-current energy storage voltmeter, an alternating-current energy storage voltmeter and a 220V relay, and the alternating current and the direct current of the energy storage are automatically switched to different meters through the relay to be displayed.

The permanent magnet switch module comprises an on-position indicator lamp B17, an off-position indicator lamp B18, a manual closing button B19, a manual opening button B20, a closing input B22, a closing public B23, an opening input B24, an opening public B25, a remote signaling input C26, a remote signaling public C27, a remote signaling input D28 and a remote signaling public D29. The upper diagram is a simulation wiring diagram of the permanent magnet switch, and the state of the switch opening and closing and the switch position is simulated through the interlocking of two relays. The two ac contactors are connected through the interface of the input and output terminals of the contactor to form a simple interlock circuit. When the single-side alternating current contactor gives a signal, the other alternating current contactor is locked, so that the switching-on and switching-off mode of the permanent magnet switch is simulated. And then, one path of signal is taken from the upper surface of the alternating current contactor, and the signal is combined with a simple 24Vled driving circuit to indicate an opening and closing LED lamp.

The change-over module comprises an input change-over 21 for adjusting the coils for different voltage levels. In order to make a set of analog switch meet the simulation of switches with different voltage grades, three groups of coils with different voltage grades DC24V/DC48V/AC220V are used together, and all the switch models on the market at present are included. The figure includes three coils of 24V brake separating coil, 48V brake separating coil and 220V brake separating coil, which simulate the driving receptor parts of the spring operating mechanism with three voltage levels. The three voltage grades are switched through the coil change-over switch, so that the requirements of different spring-operated switch models on the voltage grades are met.

The elastic operation switch module comprises a closing indicator lamp A13, an opening indicator lamp A14, a manual closing button A15 and a manual opening button A16. The working principle is as follows: the closing input refers to the closing output of the controller, the opening input refers to the opening output of the controller, and the sensor of the coil is AC220V and is equivalent to a conduction switch. The switching-on and switching-off of the analog switch mainly comprises two relays of AC220V and one contactor of AC220 v. Assuming that the coil of the analog switch is DC24V, the default analog switch is in an open state, when a controller gives a closing command (closing output DC24V +), the closing coil acts, the closing coil sensor is switched on, the closing relay coil is electrified (a normally open point is switched on), the contactor coil is electrified (a normally open point is switched on), at the moment, the contactor keeps an attraction state, the closing relay also keeps the attraction state, and thus the analog switch is kept in an on position. When the controller gives a switching-off command, the switching-off coil acts, the switching-off coil sensor is switched on, the switching-off relay coil is electrified (the normally-closed point is disconnected), and the AC 220V-of the contactor coil is connected with the normally-closed point of the switching-off relay, so that the contactor coil is electrified (the normally-open point is restored to the original position) at the moment, the switching-on relay coil is electrified (the normally-open point is restored to the original position), and the switch is restored to the original position (the switching-off position) at the moment. The alternating current contactor is controlled through the separating brake relay and the closing relay respectively, and the separating brake indicator lamp is used for indicating the separating brake state and the closing brake state.

The power supply part of the device can directly adopt an on-column 220V power supply, one end of the power supply is connected with a PT side navigation plug through a PT bus-bar wire matched with each manufacturer to take power, and the other end of the power supply is connected with a three-core power supply connector to be directly inserted into the device. The switching output signal and the switching position remote signaling signal of the controller are directly connected to the equipment through the aerial patch switching line. The embedded voltage switching-on and switching-off circuit analog controller of the device is utilized to switch on and off, and then the actual switching action condition is simulated through the output of the switching signal, so that the purpose of carrying out logic test and modification on the terminal on site is achieved.

The manual opening button is used for simulating an opening and closing handle on the switch. The relay and the contactor are combined to form the self-locking of the on-off of the analog switch coil, the driving voltage converter is used for selecting the driving voltage of the coil, and the coil sensor is used for transmitting the signal of the action of the coil, so that the state of the analog switch is realized.

The utility model discloses the regulation and control parameter meaning does:

closing input: the controller closes the output (coil drive voltage +).

Closing the switch public: controller on-off gate common terminal (coil driving voltage-)

Switching-off input: controller open-gate output (coil driving voltage +)
