To achieve these goals, the utility model is by the following technical solutions:
A kind of photovoltaic DC-to-AC converter of integrated DC power supply unit, comprise rack, rack is divided into left side and right side two parts, in rack, left bottom is furnished with Direct Current Distribution Unit 1, the input of described Direct Current Distribution Unit 1 is positioned at rack left side bottommost, for the input of whole photovoltaic DC-to-AC converter, be connected with outside DC suppling equipment or assembly, above Direct Current Distribution Unit 1, be furnished with power inverting unit 2, the input of described power inverting unit 2 is connected with the output of described Direct Current Distribution Unit 1, above power inverting unit 2, be furnished with control unit 3, described control unit 3 is connected with switching tube and the heat-sink unit of the power model of photovoltaic DC-to-AC converter, control the operation of its blower fan, top on rack left side and right side is furnished with respectively the heat-sink unit 4 that whole rack is carried out to exhausting heat radiation, be furnished with at the middle part on rack right side and be connected with control unit 3 and to the control power supply unit 5 of its power supply, the arranged beneath of controlling power supply unit 5 in the bottom on rack right side has the output unit 6 of interchange, the end of incoming cables of described photovoltaic DC-to-AC converter is positioned at the lower left of rack, leading-out terminal is positioned at the lower right of rack.
Described Direct Current Distribution Unit 1 adopts two installing racks that are arranged above and below, and for DC distribution module DC circuit breaker used is installed, this installing rack can be installed multiple DC circuit breakers as required.
The utility model compared to the prior art, possesses following advantage:
1. inverter and DC power distribution cabinet unite two into one, and realize integrated design, and convenient transportation, installation process are quick and easy.
2. the once mounting that realizes inverter is used, and does not exist and the problem that is used in conjunction with of DC power distribution cabinet, has avoided the compatibility issue of two kinds of products.
3. save cabinet design, the buying of DC power distribution cabinet, save the device requirement of the direct current input circuit breaker of former inverter, greatly reduce costs.
4. meet the requirement of multi-circuit breaker input, can realize freely switching of different input ways, without the structure that redesigns power supply unit, avoid the DC power distribution cabinet design process of various non-standard configurations.
5. the power density of inverter improves, and saves installing space, can make the integrated machine room of MW class or the overall dimension in civil engineering room greatly dwindle, and further reduces costs.
