One end of three adjustment portions 603 is provided with hook 612, to be connect by hook 612 with hook portion 501.
Preferably, the quantity and hook portion 501 of adjusting component 600 and the quantity of following fixing grooves 402 are equal, and
It adjusts component 600 and hook portion 501 and fixing groove 402 is located on the same line.
Further, disconnecting link bar 100 close to ladder section one end setting it is fluted, the first fixing seat 400 by groove with
Disconnecting link bar 100 connects.
Further, card slot 401 and at least two fixing grooves 402, two fixing grooves are provided in the first fixing seat 400
402 are symmetrical set relative to card slot 401, and card slot 401 and groove are clamped.
Further, the first adjustment portion 601 is provided with annulus 611 far from one end of third adjustment portion 603, to pass through annulus
611 are clamped with fixing groove 402.
Specific operation process is sheathed in fixing groove 402, it is therefore prevented that annulus by the annulus 611 of the first adjustment portion 601
611 move left and right relative to fixing groove 402；In addition, being mounted in hook portion 501 by the second adjustment portion 602, and due to first
Fixing seat 400 is clamped by the groove of card slot 401 and disconnecting link bar 100, thus when the first adjustment portion 601 and the second adjustment portion 602
When vertically moving relative to third adjustment portion 603, all displacements can be passed through to the second fixing seat 500 relative to disconnecting link bar
100 is mobile, improves work efficiency.
Disconnecting link power failure is overhauled because of equipment fault or big light maintenance need of work every year for present power supply bureau
Space-number is about 5, by taking a 220kV outgoing line interval of 220kV substation as an example, a 220kV outgoing line interval voltage rating
For 252kV, rated current 3150A, power factor (PF) is calculated with 0.9, number required for such interruption maintenance be 10 people (including
The personnel such as maintenance, test and producer), service personnel, for 50 yuan/hour, is used for knife using provided in this embodiment with average salary
The interruption maintenance time that 1 is spaced was shorten to 1 day by 2 days, reduces power off time and power more by the more changing device of lock spring
Amount, the interruption maintenance time of reduction are 1 day.The economic benefit of generation is as follows:
The reduction power off time at 1 interval: 1 day × for 24 hours=for 24 hours.
More power supply volumes: 5 interval × 252kV × 3150A × 0.9 × for 24 hours=9525600kWh.
Electricity charge profit with every degree electricity is 0.3 yuan of benefit for calculating more power supplies and generating: 9525600kWh × 0.3 yuan/
Ten thousand yuan of kWh=286.768.
Save human cost are as follows: 50 × 8h × 1 day × 10 people × 5 are spaced=2 ten thousand yuan.
Therefore the benefit summation that the human cost that can be saved every year and more power supply volumes generate is about are as follows: 286.768+2=288.768
Wan Yuan.
