Abstract
The invention discloses an earthing switch for a 10 kilovolts (KV) capacitor whole set cabinet. The earthing switch comprises a bottom frame and four groups of earthing switch blades which are evenly distributed on the bottom frame side by side, and the four groups of earthing switch blades are respectively three-phase earthing switch blades and a neutral point earthing switch blade. A traditional mode that a neutral point is connected to the earth through an earthing wire is changed to be the mode that the switch blades are used for achieving, so that electric discharging and earthing of the capacitor without opening a rear cabinet door of a capacitor combination cabinet is achieved, the fact that operators accidentally touch the neutral points which are not discharged before the neutral point is discharged and earthed is avoided, and the personnel safety of the operators is guaranteed. Meanwhile, operation is simplified, and the operators can operate conveniently. The number of needed earthing wires in loop hauling of the capacitor is reduced.
Description
Technical field
The present invention relates to a kind of high voltage power transmission and transforming device, relate in particular to a kind of earthed switch for 10 kilovolts of capacitor complete cabinets.
Background technology
In 10 kilovolts of capacitor complete cabinets commonly used, first, second group capacitor all has a cover ground connection switch now, and this earthed switch is used for capacitor body is carried out reliable three-phase ground.
And when capacitor overhauled, the necessary ground connection of its neutral point prevented the personal injury that causes due to the discharge of capacitor neutral point.But because the earthing position of first, second group capacitor neutral point in 10 kilovolts of capacitor complete cabinets is generally all relatively hidden, operating personnel tear hanging earthing conductor open and bother very much, have both affected operating efficiency, more operating personnel's safety is brought certain hidden danger.
Summary of the invention
Purpose of the present invention provides a kind of earthed switch that is used for 10 kilovolts of capacitor complete cabinets simple in structure, easy to use exactly in order to address the above problem.
The object of the present invention is achieved like this:
A kind of earthed switch for 10 kilovolts of capacitor complete cabinets of the present invention, comprise a underframe and be fixed on described underframe and be three-phase inlet wire insulator and the three-phase outlet insulator that two rows distribute, on the line insulator, terminal block is housed respectively every, be provided with a contact knife every into and out of between the line insulator, the fixing electric conductor in this contact knife one end and outlet insulator top is hinged, and the other end is connected with the mobilizable contact of electric conductor that inlet wire insulator top is fixed; described electric conductor is fixedly connected with terminal block, advancing, on underframe between outlet insulator, installation one runs through the rotating spindle of described underframe, described rotating spindle advances mutually every, position between outlet insulator is fixed with connecting plate, the other end of this connecting plate is hinged on respectively on insulated tension pole, the other end of this insulated tension pole is hinged on the middle part of each contact knife, described earthed switch also comprises neutral point inlet wire insulator, the neutral point outlet insulator, the neutral point terminal block, the neutral point contact knife, neutral point connecting plate and neutral point insulation pull bar, wherein
described neutral point inlet wire insulator is fixed on described underframe and with described three-phase inlet wire insulator and is positioned at same row, described neutral point outlet insulator is fixed on described underframe and with described three-phase outlet insulator and is positioned at same row, described neutral point terminal block is installed on respectively described neutral point and advances, on outlet insulator, described neutral point contact knife is located at neutral point and is advanced, between outlet insulator, the fixing electric conductor in one end of this neutral point contact knife and neutral point outlet insulator top is hinged, the fixing mobilizable contact of electric conductor in the other end and neutral point inlet wire insulator top is connected, one end of described neutral point connecting plate is fixed on described rotating spindle and is positioned at neutral point, position between outlet insulator, the other end is hinged on described neutral point insulation pull bar, the other end of described neutral point insulation pull bar is hinged on the middle part of described neutral point contact knife.
The present invention changes into traditional neutral point by plug-in strip by the mode of ground connection and realizes, thereby realized not opening door after the capacitor bank cabinet and to capacitor discharge ground connection, thereby avoided before neutral point discharge ground connection operating personnel's mistake to touch the not neutral point of discharge, guaranteed operating personnel's life safety.Simplified simultaneously operation, the handled easily personnel operation.And the number of required earth connection when having reduced the capacitor loops maintenance.
