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 changes 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 existence of little bus to the puzzlement changing protection screen.The way of current routine is: first cross-over connection bus will change the part that protection screen needs to cut off, and then cuts off little bus, then changes protection screen.
Under normal circumstances, there is not breakpoint in the middle of the little bus of every root in little bus marshalling, cuts off little bus finally again method logical for little bus jumping, protection screen top finally can be caused irregular if adopted.
Summary of the invention:
Technical problem to be solved by this invention is: provide a kind of transformer station not cut off the method for little bus replacing protection screen.
The technical scheme that the present invention takes for technical solution problem is:
The method that little bus changes protection screen is not cut off by transformer station, and new protection screen is identical with old protection screen height, and its concrete steps are as follows:
A, operating procedure before exiting old protection screen:
(1), old protection screen coiled hair of dismantling, protection screen top suspension ring of dismantling;
(2), bulk waste plastic cloth is set between hand and little bus as insulating materials, removes little bus leading and roll off the production line; Former little bus leading rolls off the production line and is connected on the screw of auxiliary bus-bar joint row side, can cut off little bus leading and roll off the production line, be wrapped by exposed the end of a thread insulating tape.
(3), dismantle for the terminal base screw of the little bus in fixing screen top, little bus and base and protection screen thereof are departed from;
(4), after wiring all in protection screen are all removed, fixed screw bottom protection screen is all dismantled;
B, operating procedure after exiting old protection screen:
(5), all dismantle removing the part the end of a thread stayed when little bus leading rolls off the production line, by screw tightening;
(6), according to the position of new protection screen bottom mounting apertures, boring on channel-section steel tapping;
C, operating procedure before new protection screen is installed:
(7), by new protection screen coiled hair dismantle, new protection screen top upper lift ring of dismantling;
(8), measure the hole that auxiliary bus-bar joint is fixed on old protection screen top, hole as it is on new protection screen top and tapping;
The installation steps of D, new protection screen:
(9), by new protection screen horizontal sliding enter former installation site, be screwed new protection screen, screen top auxiliary bus-bar joint is fixed on screen apical pore;
(10), by new protection screen top drawing reaches the standard grade is connected on the screw of screen top terminals row top, reduces wiring degree of danger;
(11) other wiring of new protection screen and installment work, is completed.
At the security step exiting old protection screen be:
(1), little bus is rebuilding, exiting before with regard to protection screen, arranges bulk waste plastic cloth as insulating materials between two-layer little bus;
(2), guard little bus safe condition, exit original position by flat for protection screen, complete and change protection screen work.
Positive beneficial effect of the present invention is:
1, the present invention utilizes the condition that new protection screen is identical with old protection screen height, after new installation protection screen, the little bus on screen top can not be raised.After old protection screen internal wiring is removed; screen top is got rid of from rear with auxiliary bus-bar joint; protection screen is released original position; the annex (coiled hair, suspension ring) that new protection screen top is installed is dismantled; new protection screen horizontal sliding is entered installation site; and screen top auxiliary bus-bar joint row is fixed on new protection screen, reach the object more renewing protection screen.
2, the on-the-spot demand fulfillment condition of the present invention: 1. old protection screen is fixed on channel-section steel by the mode of screw tapping; 2. new protection screen is identical with old protection screen height.
3, present invention obviates and cut off the uppity working link of this dangerous spot of little bus, adopt and do not cut off little bus and change protection screen, the dangerous spot of the course of work is easily controlled, makes protection screen replacing construction shorten to 2.5 days simultaneously, save 1.5 days durations.
Cut off little bus to change the method for protection screen and the workload of the inventive method and be compared as follows:
Detailed description of the invention:
Embodiment: the method that little bus changes 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 as follows:
A, operating procedure before exiting old protection screen:
(1), old protection screen coiled hair of dismantling, protection screen top suspension ring of dismantling;
(2), bulk waste plastic cloth is set between hand and little bus as insulating materials, removes little bus leading and roll off the production line; Be connected on the screw of auxiliary bus-bar joint row side because former little bus leading rolls off the production line, little bus leading can be cut off if desired and roll off the production line, exposed the end of a thread insulating tape is wrapped;
(3), dismantle for the terminal base screw of the little bus in fixing screen top, little bus and base and protection screen thereof are departed from;
(4), after wiring all in protection screen are all removed, fixed screw bottom protection screen is all dismantled;
B, operating procedure after exiting old protection screen:
(5), all dismantle removing the part the end of a thread stayed when little bus leading rolls off the production line, by screw tightening;
(6), according to the position of new protection screen bottom mounting apertures, boring on channel-section steel tapping;
C, operating procedure before new protection screen is installed:
