Abstract
The invention discloses a method for changing a protective screen without cutting a small bus for a transformer substation. By means of condition that a new protective screen is as high as the old one, the small bus at the top of the screen cannot be lifted up after the new protective screen is installed. The method comprises the steps of: pushing the protective screen out of the original place after detaching a connecting wire in the old protective screen and separating a small bus terminal row from the top of the screen; detaching an accessory installed at the top of the new protective screen; pushing the new protective screen into the installing place and fixing the small bus terminal row at the top of the screen on the new protective screen so as to achieve the purpose of changing the protective screen. According to the method disclosed by the invention, a work loop in which the dangerous point of cutting the small bus is not easy to control is avoided, the protective screen is changed without cutting the small bus so that the dangerous point in the working process is easy to control; meanwhile the time for changing the protective screen is shortened to 2.5 days, and thereby the construction period is shortened by 1.5 days.
Description
Technical field:
The present invention relates to a kind of transformer station and do not cut off the method that little bus is changed protection screen.
Background technology:
Carry out in the work of protection screen replacing in transformer station, protection screen is changed the most nerve-wracking part and is surely belonged to the puzzlement of the existence of little bus to the replacing protection screen.Conventional at present way is: first cross-over connection bus will be changed the part that protection screen need be cut off, and cuts off little bus then, changes protection screen again.
Generally, there is not breakpoint in little bus marshalling in the middle of the every little bus, cuts off the last method of leading to little bus jumping again of little bus if adopt, and finally can cause the protection screen top irregular.
Summary of the invention:
Technical problem to be solved by this invention is: provide a kind of transformer station not cut off the method that little bus is changed protection screen.
The technical scheme that the present invention is taked for the technical solution problem is:
The method that little bus is changed protection screen is not cut off by a kind of transformer station, and new protection screen is identical with old protection screen height, and its concrete steps are following:
A, the operating procedure before withdrawing from old protection screen:
(1), the old protection screen coiled hair of dismantling, the protection screen top suspension ring of dismantling;
(2), bulk waste plastic cloth is set as insulating material between hand and little bus, remove little bus downlead; Former little bus downlead is connected on the screw of auxiliary bus-bar joint row side, can cut off little bus downlead, will expose the end of a thread and wrap with insulating tape.
(3), dismantling is used for fixing the terminal base screw of the little bus in screen top, and little bus and base thereof and protection screen are broken away from;
(4), behind all wiring complete removals in the protection screen, protection screen bottom fixed screw is all dismantled;
B, the operating procedure after withdrawing from old protection screen:
(5), part the end of a thread of staying in the time of will removing little bus downlead all dismantles, with screw tightening;
(6), according to the position of new protection screen bottom installing hole, boring and tapping on channel-section steel;
C, the operating procedure before new protection screen is installed:
(7), new protection screen coiled hair is dismantled new protection screen top upper lift ring;
(8), measure the fixedly hole of auxiliary bus-bar joint, old protection screen top, in boring and the tapping as it is of new protection screen top;
The installation steps of D, new protection screen:
(9), former installation site is entered in new protection screen horizontal sliding, fix new protection screen with screw, screen top auxiliary bus-bar joint is fixed on the screen apical pore;
(10), new protection screen top drawn to reach the standard grade be connected on the screw of screen top terminals row top, reduce the wiring degree of danger;
(11), accomplish other wiring of new protection screen and installment work.
At the security step that withdraws from old protection screen be:
(1), little bus is double-deck the layout, before withdrawing from regard to protection screen, bulk waste plastic cloth is set as insulating material between two-layer little bus;
(2), the little bus safe condition of monitoring, with the flat original position that withdraws from of protection screen, accomplish the protection screen work of changing.
Positive beneficial effect of the present invention is:
1, the present invention utilizes new protection screen and the identical condition of old protection screen height, newly protection screen is installed after, can the little bus on screen top not raised.After old protection screen internal wiring dismounting; After screen top and auxiliary bus-bar joint are got rid of and are left; Protection screen is released original position, the annex (coiled hair, suspension ring) that install on new protection screen top is dismantled, the installation site is gone in new protection screen horizontal sliding; And will shield top auxiliary bus-bar joint row and be fixed on the new protection screen, reach the purpose that more renews protection screen.
2, scene of the present invention need satisfy condition: 1. old protection screen is to be fixed on the channel-section steel with the mode of screw with tapping; 2. new protection screen is identical with old protection screen height.
3, the present invention has avoided cutting off the uppity working link of this dangerous spot of little bus, adopts and does not cut off little bus replacing protection screen, and the dangerous spot of the course of work is controlled easily, makes the protection screen replacing time shorten to 2.5 days simultaneously, practices thrift 1.5 days durations.
Cutting off little bus, to change the workload of method and the inventive method of protection screen following:
Embodiment:
Embodiment: the method that little bus is changed protection screen is not cut off by a kind of transformer station, and new protection screen is identical with old protection screen height, and its concrete steps are following:
A, the operating procedure before withdrawing from old protection screen:
(1), the old protection screen coiled hair of dismantling, the protection screen top suspension ring of dismantling;
(2), bulk waste plastic cloth is set as insulating material between hand and little bus, remove little bus downlead; Because former little bus downlead is connected on the screw of auxiliary bus-bar joint row side, can cut off little bus downlead in case of necessity, will expose the end of a thread and wrap with insulating tape;
(3), dismantling is used for fixing the terminal base screw of the little bus in screen top, and little bus and base thereof and protection screen are broken away from;
(4), behind all wiring complete removals in the protection screen, protection screen bottom fixed screw is all dismantled;
B, the operating procedure after withdrawing from old protection screen:
(5), part the end of a thread of staying in the time of will removing little bus downlead all dismantles, with screw tightening;
(6), according to the position of new protection screen bottom installing hole, boring and tapping on channel-section steel;
C, the operating procedure before new protection screen is installed:
