Accompanying drawing explanation
Fig. 1 is structural principle block diagram of the present utility model.
Fig. 2 is the accurate simultaneous interconnecting winding diagram of distributed power source access cabinet of the present utility model.
Embodiment
As shown in Figure 1, the utility model is achieved like this, it comprises photovoltaic array, photovoltaic combiner box, photovoltaic distribution cabinet, transformer, load I, distributed power source access cabinet, electrical network and load II, wherein, photovoltaic array, photovoltaic combiner box and photovoltaic distribution cabinet are connected successively, photovoltaic distribution cabinet is connected with load I with transformer respectively again, and transformer, electrical network and load II are all connected to distributed power source access cashier's office in a shop;
Described distributed power source access cabinet is comprised of one group of switch cubicle, and switch cubicle comprises incoming line cabinet, PT cabinet, metering cabinet and outgoing line cabinet, and the cabinet of switch cubicle consists of bus-bar room, circuit breaker cart Shi Ji cable vault.
The external cabling of described distributed power source access cabinet totally 4 pairs of terminals, and from right to left 1, the same famous prime minister of two pairs of terminal connecting system sides of 2 and generating pusher side signal source, what have 100V voltage transformer connects A, B two-phase, no-voltage instrument transformer connect A phase and 0 line; On A phase connecting terminal, arrange, under B phase or 0 line connecting terminal, arrange, input signal is same famous prime minister.
The course of work of the present utility model and execution mode are such, the direct current sending by photovoltaic array, after photovoltaic combiner box, photovoltaic distribution cabinet, directly accesses load I or by transformer, accesses distributed power source access cabinet and use interconnection technology access electrical network or load II.
As shown in Figure 2, this device external cabling totally 4 pairs of terminals.From right to left 1, the same famous prime minister of two pairs of terminal connecting system sides of 2 and generating pusher side signal source, what have 100V voltage transformer connects A, B two-phase, no-voltage instrument transformer connect A phase and 0 line.On A phase connecting terminal, arrange, under B phase or 0 line connecting terminal, arrange, notice that input signal must be same famous prime minister.If right and wrong phase of the same name, or reverse polarity connection, can cause non-Switching Synchronization.The 4th pair of terminal is combined floodgate output contact, in internal relay when action, is by this junction closure, when console switch is electromagnetism closing switch or electric air switch, can directly to it, control, but must determine that the output contact capacity of this device is enough, the contact burning of making provision against emergencies produces adhesion and causes non-Switching Synchronization.When console switch is hand switch, should install A.C. contactor additional, grid-connected by controlling A.C. contactor, its capacity is 1/5 to 1/3 of generator rated capacity.A.C. contactor should be in parallel with isolating switch, and air switch can be used as grid-connected backup protection like this.
