Embodiment
As shown in Figure 1, the removable transformer station of tower machine, the mode of connection of this transformer station inside is: high-tension cable inlet wire 1 is connected to high voltage isolator 2, vacuum circuit-breaker 3, current transformer 4, transformer 5 successively, and the other end of transformer 5 connects low-voltage equipment; Described high-tension cable end of incoming cables also is parallel with electrification display 1 and lightning arrester 7, the end that described high voltage isolator 2 connects vacuum circuit-breaker 3 is connected with the high-tension fuse 8 and the voltage transformer 9 of series connection, is connected with electrification display 2 10 between described current transformer 4 and the transformer 5;
Also be provided with computer integrated protection in the hyperbaric chamber of this transformer station, the input of computer integrated protection is connected with the output of current transformer 4, voltage transformer 9, and the output of computer integrated protection is connected with the controlled terminal of vacuum circuit-breaker 3;
Direct current cabinet also is installed in the low-pressure chamber of this transformer station, and the direct current output of direct current cabinet is connected with the power supply of computer integrated protection.
The casing top of this transformer station is equipped with mobilizable downlead support.
The box frame of described transformer station adopts welded structure; be installed in the top of tower machine and the steel construction of tower machine and become one; have very high harmony and dynamic stability; to directly introduce the hyperbaric chamber from the cable that high-voltage fence attracts; be equiped with comprehensive safety precautions in the hyperbaric chamber; and there is long-range supervisory control system to cooperate with it, inserts the power consumption equipment of tower machine system then from transformer station's low-pressure side, satisfy concentrated load power supply and the demanding distribution requirement of power supply quality.
The advantage of this transformer station has:
