Abstract

Cabinet of a complete high-voltage switchgear with a two-position disconnector-earthing switch, characterized in that a screw mechanism is located in the low-voltage compartment, having an exit to the front panel, a retractable rod of which is connected via an intermediate shaft to the insulation rod of each phase of the two-position disconnector-ground electrode, consisting of a movable contact , two fixed contacts of the disconnector and the earthing knife.

Description

The utility model relates to electrical engineering, namely to the design of enclosures of complete switchgears in the future switchgear) with vacuum circuit breakers.
The design of switchgear with a switch and an earthing switch is known (see ETALON Complete Switchgear. Technical Information WWW.TAVRIDA.RU) with the operational grounding circuit of the main circuit through a vacuum chamber. This design is distinguished by its large dimensions and control complexity, since a three-position drive of the earthing switch-disconnector with a complex drive mechanism is used.
The switchgear cabinet is known (see patent No. 142071 dated 01/10/2013 H02B 13/00), in the high-voltage compartment of which there is a vacuum circuit breaker, disconnector, and in the control compartment, drives of a vacuum circuit breaker, ground electrode and disconnector. The drive of the ground electrode through a system of levers, traction and spring-link mechanism is connected with the movable contact of the ground electrode. The disconnector contains two fixed contacts and one movable. The first fixed contact is connected to the movable contact of the vacuum chamber, and the second fixed contact is connected to the busbar. The disadvantage of this design is the large size and complexity of managing the contacts of the disconnector and ground electrode.
A switchgear is known (see patent 141036 dated 01.10.2013 H01B 13/00), containing a disconnector with movable and fixed contacts and a drive of a movable contact of the disconnector, including an electric motor with a rod, an insulating rod of a movable contact, a linkage with an axis in a horizontal plane with two fixed leverage on it. The disadvantage of this design is the difficulty of managing the contacts of the disconnector and the ground electrode.
The objective of the utility model is to reduce the size, increase the safety and ease of operation of the cabinet of the complete switchgear.
The problem is solved due to the fact that in the low-voltage compartment of the switchgear cabinet of high voltage there is a screw mechanism that has access to the front panel of the cabinet, the retractable rod of which is mechanically connected through the intermediate shaft to the insulation rod of each phase of the two-position disconnector-earthing switch, consisting of a movable contact, two fixed contacts of the disconnector and the earthing knife. A fast-acting earthing switch is excluded, if a short circuit occurs (because the disconnector-earthing switch is already grounded), the arc will be extinguished in a vacuum chamber, which can be turned off by a switch without any consequences. At the same time, a place for the necessary component equipment is freed up in the high-voltage compartment.
The utility model is illustrated by drawings. In FIG. 1 shows a section of a switchgear cabinet in the “on” position. In FIG. 2 shows the circuit breaker-earthing switch in the “on” position. In FIG. 3 shows a section of the switchgear cabinet in the off position. In FIG. 4 shows the circuit breaker-earthing switch in the off position.
Switchgear cabinet 1 contains a two-position disconnector-earthing switch, consisting of a movable contact 2, two fixed contacts 3, 4 and an earthing knife 5. The drive of the switch-disconnector-earthing switch is located in the low-voltage compartment 6 of cabinet 1 of the switchgear and includes a screw mechanism 7 with access to the front panel , its retractable rod 8 through the intermediate shaft 9 is mechanically connected to each phase of the on-off disconnector-earthing switch through levers 10, 11 and the insulating rod 12.
The device operates as follows. In the on position, the cables are connected to the busbars through the vacuum chambers of the switch (not shown), which in turn are connected by current collectors to the fixed contacts 3, 4 of the on-off disconnector-earthing switch, the movable 2 and the fixed contacts 3, 4 are closed. If grounding is necessary, for example, during repair work or when a command is sent to turn off the power, the contacts of the vacuum chambers of the circuit breaker (not shown), the screw mechanism 7, which can be controlled either electrically or manually, through the intermediate shaft 8, levers 9, 10 and isolation the rod 12 opens the movable contact 2 with the fixed contacts 3, 4 and closes the movable contact 2 to the grounding knife 5.
