Abstract
The invention provides a control method of a substation water pump, which is used for a drainage system of a substation and for controlling the water pump to open and close. Because the control method of the invention is adopted, the problem of auxiliary contact rustiness can be completely avoided, thereby ensuring the normal action of the water pump and improving the reliability of the drainage system of the substation.
Description
Technical field
The present invention relates to water pump control method in a kind of power engineering, relate in particular to a kind of substation drainage system water pump control method.
Background technique
The cable floor of electric substation is positioned at underground, and rainwater weather brings ponding through regular meeting to cable floor, if the ponding of cable floor can't discharge smoothly, ponding will bring very big influence to the insulation of cable and related accessories thereof.The safe operation of reduction meeting serious threat electric substation of insulation, thereby with water pump cable floor ponding to be emitted in time be very crucial.
The equipment that is used for the control of pump action comprises the spacing bucket of auxiliary contact device, ball float and ball float, and find that in actual use auxiliary contact can get rusty and then cause adhesion, thereby make the water pump can't regular event, and iron ball float easily gets rusty, can cause ball float stuck in the spacing bucket of ball float, reduce the reliability of substation drainage system.
Summary of the invention
The object of the present invention is to provide a kind of controlling method of substation water pump, this controlling method is used for new control system, can effectively avoid the corrosion of auxiliary contact, guarantees the safe operation of electric substation.
The object of the present invention is achieved like this:
The invention provides a kind of controlling method of substation water pump, described method is used for the drainage system of electric substation, this system comprises wet pit, ball float, water pump controller and the water pump that links to each other with the water pump controller circuit link to each other with the ball float circuit, comprise auxiliary contact in the described ball float, the main contact that links to each other by elastic member with auxiliary contact and be located at Metal Ball on the auxiliary contact, also has disconnecting circuit in the described ball float, this circuit is connected when main contact is in reset mode, said method comprising the steps of:
When the wet pit water level reach a certain height, ball float suspended in water, and Metal Ball breaks away from auxiliary contact, and the main contact that links to each other with auxiliary contact resets, and had connected the disconnecting circuit in the ball float, and water pump controller brings into operation, and control of pump starts draws water;
When the wet pit water level was reduced to certain altitude, ball float was in erectility, and Metal Ball presses down auxiliary contact by self gravitation, the main contact breaking circuit, and this moment, circuit was in off state, and water pump stops pumping.
Owing to adopted controlling method of the present invention, the problem that can avoid auxiliary contact to get rusty has fully guaranteed the regular event of water pump, has improved the reliability of substation drainage system.

Fig. 2 is the sectional view of ball float 2 among Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and embodiments.
Referring to Fig. 1, Fig. 2, the invention provides a kind of controlling method of substation water pump, described method is used for the drainage system of electric substation, this system comprises wet pit 1, ball float 2, water pump controller 3 and the water pump 4 that links to each other with water pump controller 3 circuit link to each other with ball float 2 circuit, comprise auxiliary contact 23 in the described ball float 2, the main contact 22 that links to each other by elastic member with auxiliary contact 23 and be located at Metal Ball 21 on the auxiliary contact 23, also has disconnecting circuit in the described ball float, this circuit is connected when main contact is in reset mode, said method comprising the steps of:
When wet pit 1 water level was reduced to certain altitude, ball float 2 was in erectility, and Metal Ball 21 presses down auxiliary contact 23 by self gravitation, main contact 22 breaking circuits, and this moment, circuit was in off state, and water pump 4 stops pumping.
When wet pit 1 water level reach a certain height, ball float 2 suspended in water, and Metal Ball 21 breaks away from auxiliary contact 23, the main contact 22 that links to each other with auxiliary contact 23 resets, connected the disconnecting circuit in the ball float 21, water pump controller 3 brings into operation, and control of pump 4 starts draws water.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technological schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
