Description
Technical field
The present invention relates to a kind of in the antitheft consumption reduction transmission system of mesolow closely.
Background technology
Present power delivery mainly relies on the transmission of high pressure or middle pressure alternating current, and carries out pressure regulation by equipment such as transformers, finally delivers to electric terminal.But this kind power transmission/transform method exists more defective in actual use, especially in electric power conveying process closely, more outstanding.Have capacitance current such as the transmission line of alternation current, cause that line loss is large, the transmission tower complex structure, circuit corridor floor space is large, the synchronous difficulty of long-distance transmissions two places electric power system, easily has the existing fault of power supply etc.Because the terminal use mostly is AC electric equipment, be prone to the phenomenon of abstraction of electricity simultaneously.Therefore say that although the mesohigh T ﹠ D Technology has used for many years, it is not optimal transmission of electricity scheme.
Summary of the invention
The object of the invention just is to overcome above-mentioned deficiency, provide a kind of in the antitheft consumption reduction transmission system of mesolow closely.
For achieving the above object, the present invention is achieved through the following technical solutions:
In the antitheft consumption reduction transmission system of mesolow closely, comprise High-voltage Incoming Cabinet, the high-voltage terminal cabinet, transformer, the low-pressure line-outgoing cabinet, the AC/DC conversion cabinet, the direct current outgoing line cabinet, transmission line, the direct current incoming line cabinet, the DC/AC inverter cabinet, exchange outgoing line cabinet, the external high pressure line is from the High-voltage Incoming Cabinet connecting system, High-voltage Incoming Cabinet and the electrical connection of high-voltage terminal cabinet, high-voltage terminal cabinet and transformer electrical connection, transformer and the electrical connection of low-pressure line-outgoing cabinet, low-pressure line-outgoing cabinet and the electrical connection of AC/DC conversion cabinet, AC/DC conversion cabinet and the electrical connection of direct current output counter, direct current output counter and the electrical connection of transmission line one end, the transmission line other end and the electrical connection of direct current incoming line cabinet, direct current incoming line cabinet and the electrical connection of DC/AC inverter cabinet, the DC/AC inverter cabinet is electrically connected with exchanging outgoing line cabinet, exchanges outgoing line cabinet and system's externally fed circuit electrical connection.
Further, described transmission line is the two-wire system DC power transmission line.
Beneficial effect of the present invention is:
1, adopt DC power transmission line, comparable conventional AC transmission line is saved 2/3-1/3 line material expense, and DC power transmission line electric pole tower structure is also simple than the three-phase alternating current transmission of electricity with capacity, and circuit corridor floor space is also little.
2, direct current transportation does not have capacitance current to produce, and can not cause loss.
3, DC power transmission line makes common alternating current equipment extremely be difficult for entering in the network of transmission of electricity, forms the power transmission and transformation network of a relative closure, effectively prevents from stealing electricity.
