For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
The utility model is a kind of capacitor compensation cabinet that uses secondary principle wiring technology, be mainly used in and solve existing capacitor compensation cabinet and cut or lock catch when changing to automatic transmission from manual as diverter switch 1SA, two skimble-scamble situations of power factor value that might show in power factor meter and auto power-factor compensating instrument ZKW are to such an extent as to produced the problem of unnecessary influence to user's use.For this reason, in the work loop of existing capacitor compensation cabinet, carry out suitable improvement.
As shown in Figure 1, be the module map in the main work loop of the utility model.The utility model mainly comprises terminal (as shown in Figure 2) that wiring uses, is installed in the current signal sampling circuit module in the incoming line cabinet, and the major loop module (as shown in Figure 3) of electric energy is provided when being used to capacitor compensation cabinet work; Be used for showing the switching show circuit module (as shown in Figure 4) of major loop module contactor folding condition; The current detection circuit module (as shown in Figure 5) of size of current when being used to measure capacitor compensation cabinet work; The voltage detecting return circuit module of voltage swing when being used to measure capacitor compensation cabinet work, and the power factor of power factor numerical value detects return circuit module (as shown in Figure 6) when being used to measure capacitor compensation cabinet work; Be used for the work loop of capacitor compensation cabinet is carried out the secondary control loop module (as shown in Figure 7) of regulating and controlling; Auto power-factor compensating instrument ZKM (as shown in Figure 8).During the connection in the loop of respectively working in the utility model, the auto power-factor compensating instrument links to each other with the secondary control loop module by the change over switch 1SA that is arranged in the secondary control loop module, switching show circuit module, voltage detecting return circuit module and secondary control loop module then are connected in turn in the major loop module, current signal sampling circuit module, the current detection circuit module, the secondary control loop module also links to each other with terminal respectively, and power factor detects return circuit module also need pass through change over switch 1SA, links to each other with voltage detecting return circuit module and terminal respectively in the mode of contact control connection.
As shown in Figure 9, be deciliter dotted state of the change over switch 1SA in the utility model under the different operating state.The utility model in use, the user only needs the using method according to traditional capacitor compensation cabinet, carries out manual, the automatic transmission on the change over switch 1SA and the adjusting of lock catch.When the user switches to automatic transmission with change over switch 1SA, three passages of 5-6 among the change over switch 1SA, 7-8 and 9-10 are connected simultaneously, remaining several channels then is in the state of disconnection, so the voltage signal in the capacitor compensation cabinet just can be transferred among the auto power-factor compensating instrument ZKM by 101-103 and two the wiring passages of 102-104 in the secondary control loop; And because the passage of the 9-10 among the change over switch 1SA is connected, these two contactings of 1A411 and N421 for this reason, again because N421 and two contact short circuits of A421 are together on the terminal, current signal just directly is input among the auto power-factor compensating instrument ZKM by 1N411 on the terminal and this short circuit passage of A421 for this reason, so just, can make the user come the numerical value of readout power factor easily by auto power-factor compensating instrument ZKM, or write down the numerical value of this power factor automatically by the microsystem of capacitor compensation cabinet, be connected the work that the power factor meter in the loop then stops to show because there not being the input of electric current and voltage signal.
When the user switches to lock catch with change over switch 1SA, and 1-2 on the change over switch 1SA and 3-4 passage just are switched on, remaining passage just remains in the off-state, auto power-factor compensating instrument ZKM just can not be by 101-103 and the 102-104 wiring passage in the secondary control loop for this reason, the voltage signal of output when receiving capacitor compensation cabinet work, and because the short circuit state is continued to keep in these two contacts of 1A411 and N421, auto power-factor compensating instrument ZKM do not have current signal to flow among the auto power-factor compensating instrument ZKM, so just can not show power factor numerical value yet for this reason.And because the 3-4 passage on the change over switch 1SA is switched on, the voltage detecting loop is just by by at two contact B601 and 607 wiring passages that form, detect the loop with power factor and link to each other, make that voltage signal can be by B601-607 wiring channel transfer in power factor meter; And because 1-2, the 3-4 passage is connected, and by adjusting on the terminal brace that N421 and A421 two contacts is carried out short circuit, make the short-circuit condition of 1N411 and A421 contact be disconnected, and power factor meter links to each other with 1A411 contact on the terminal by the current signal incoming line that is arranged on the change over switch 1SA, current signal just can be transferred in the power factor meter by this current signal incoming line for this reason, so just, in the time of can being implemented in change over switch 1SA and switching to lock catch, the user can come readout power factor value easily by power factor meter, and need not worry can be subjected to the influence that auto power-factor compensating instrument ZKM goes up the different power factor value that shows.
When the user switches to change over switch 1SA when manual, such as switch to manual in 30 ° 1 gear when putting, 1-2 on the change over switch 1SA, 3-4,11-12 passage are connected simultaneously, remaining wiring passage is then all disconnected, situation when switching to lock catch is identical, auto power-factor compensating instrument ZKM goes up non-metering and shows, and power factor meter has reading to show.Simultaneously because the connection of 11-12 passage, in secondary control loop, voltage signal is the wiring passage by being made up of line number 1,3 and 11-12 passage just, is transferred in the contactor 1KM coil for this reason, contactor 1KM main contact is closed to be connected thereby make, and this moment, capacitor C1 just began to devote oneself to work; When the user change over switch 1SA is switched to manual in 60 ° 2 gears when putting, 1-2 on the change over switch 1SA, 3-4,11-12, the 13-14 passage is switched on, and remaining wiring passage all is disconnected, situation when switching to manual 1 grade is identical, auto power-factor compensating instrument ZKM goes up non-metering and shows, and power factor meter has reading to show, simultaneously since 11-12 and 13-14 passage connected respectively, for this reason when capacitor C1 starts working, in secondary control loop, voltage signal also need pass through by line number 1, the 5 wiring passages of forming with the 13-14 passage, be transferred in the contactor 2KM coil, contactor 2KM main contact is closed to be connected thereby make, and this moment, capacitor C2 just began to devote oneself to work; And it is manual corresponding with the capacitor number because change over switch 1SA is when design, be divided into these 10 scalable shelves of 1-10, for this reason according to said method, the user only need by change over switch 1SA is adjusted to manual in corresponding the adjusting on the shelves, just actual needs that can be when using, come successively during capacitor with different numbers puts into operation, thereby satisfy the compensation requirement of capacitor box by the mode of manual compensation.
