Description
Technical field
The present invention relates to field of electrical equipment, and in particular to inverter bottom of cabinet bulk T shape is converged in a kind of preassembled transformer station
Flow bus device and a kind of prepackage type including inverter bottom of cabinet bulk T shape bus rod device in the preassembled transformer station
The inverter cabinet of substation.
Background technique
In the power transmission and transformation system of photovoltaic power generation, needs largely to be equipped with inverter apparatus, transformer, high-voltage switch gear and set
The standby preassembled transformer station waited, wherein inverter apparatus is extremely important component part, photovoltaic module is issued straight
Galvanic electricity is changed into satisfactory low-voltage AC, then after boosting to High Level AC Voltage by transformer, by high-tension switch gear
Deliver the power to power grid.In view of the amount capacity limit of inverter apparatus, inverter needed for every preassembled transformer station
Equipment generally rearranges a row by more and forms, and the alternating current that every inverter apparatus bottom of cabinet bulk exports is collected in one
It rises, conveys electric energy to the low-pressure side of transformer.
The preassembled transformer station inverter apparatus of the photovoltaic power generation of present industry same type, by every inverter apparatus cabinet body
The alternating current of bottom output pools together mode generally by two ways, and one is be connected to change by many low-voltage cables
On the busbar connector of depressor low-pressure side, another way is that the alternating current exported by every inverter apparatus bottom of cabinet bulk is pooled to
The low-pressure side of transformer is connected to after rectangular bus bar, above two mode has the following disadvantages:
One, by the way of on the busbar connector that a plurality of low-voltage cable is connected to step down side:
(1) inverter apparatus number of units is more, and there are many required low-voltage cable quantity, complex manufacturing technology, heavy workload；
(2) low-voltage cable channel space is small, complex-shaped, the bending of cable and fixed difficulty；
(3) low-voltage cable connects difficult in step down side；
(4) the connection type higher cost of low-voltage cable, maintenance are difficult.
Two, in such a way that rectangular bus bar is connected to the low-pressure side of transformer:
(1) long side of rectangular bus bar and different widths are larger, and horizontal and vertical bending strength, mechanical strength etc. also differ
It is very big.Under normal operating conditions, the operating current that three-phase bus rod passes through is smaller for equipment, by electric current generate electric power compared with
Small, the influence to rectangular bus bar is little；If equipment is in the case where accident condition (as occurred short trouble), fault current is general
Tens of thousands of amperes or bigger can be risen to, the electric power generated between bus is quite big, not such as the fixing intensity of bus and supporter
It is enough, it is easy to its supporter be destroyed, bigger secondary accident is caused；
(2) fixed form of rectangular bus bar needs out mounting hole, the current-carrying for increasing manufacture difficulty, reducing rectangular bus bar
Amount, can cause to generate heat；
(3) security protection of three-phase bus rod is more difficult, and maintenance is also inconvenient.
Summary of the invention
