Voltage-drop-free bus short-circuit isolation system and bus equipment short-circuit protection method
ActiveCN119231436Areduce load capacityGuaranteed loading capacityData switching current supplyArrangements responsive to excess currentControl signalControl engineering
The invention discloses a voltage-drop-free bus short-circuit isolation system and a bus equipment short-circuit protection method. The system comprises a protection control circuit, a recovery control circuit, a first switch, a second switch and a self-recovery fuse. The first switch and the resettable fuse are connected in series on the first bus and jointly serve as a short-circuit isolation assembly to be connected between the bus end and the equipment end; the protection control circuit is connected in parallel with the short-circuit isolation assembly. The recovery control circuit is connected in parallel between the first bus and the second bus of the bus end, and is connected with the first bus through the second switch; the protection control circuit is used for controlling the relay to act through the relay coil during electrification; the recovery control circuit is used for outputting a relay control signal to the protection control circuit when being electrified; the first switch is a normally-closed end of the relay, and the second switch is a normally-open end of the relay. By adopting the above technical scheme, circuit break protection can be carried out when the equipment end is short-circuited, and normal power supply and communication of the equipment end can be automatically recovered when a fault is removed.

A telescopic tower crane with an attachment mechanism and a working method thereof belong to the technical field of tower cranes of construction machinery. The tower crane includes an installation base, a lifting hydraulic pump station, a climbing frame, a main arm, a main arm attachment mechanism, a main winch of the arm and a counterweight. The main arm attachment mechanism is used to assist the stability of the main arm through the building under construction; the arm is a telescopic arm, and a cable is provided on the telescopic arm, one end of which is connected to the telescopic arm. The other end of the cable is hinged to the cable winch arranged behind the telescopic arm through the main arm top bracket to provide tension. The cable tightens the telescopic arm to reduce the stress on the telescopic arm. The length of the arm can be reduced, which is suitable for operation in a narrow space. The main arm attachment mechanism realizes auxiliary support for the main arm, avoids the overturning of the main arm, and reduces the overturning moment of the main arm. The auxiliary mechanism can move relative to the main arm in the vertical direction, which avoids the gravity of the main arm acting on the attached object and reduces the damage to the attached building.
