Description

The utility model relates to electrical engineering, and more specifically to closed high-voltage transformer substations of 110 kV.

Known module closed high-voltage transformer substation containing busbars, disconnectors, circuit breaker, current transformer, bushing and support insulators (copyright certificate RU 801166 IPC H02B 7/00, published 01/30/1981).

To service the equipment inside such a module, it is necessary to disconnect the power from the entire module.

The objective of this utility model is to develop a module for a high voltage transformer substation, the design of which allows preventive work when disconnectors and circuit breakers are disconnected without completely disconnecting the module.

The problem is solved due to the fact that the module of the high-voltage transformer substation, which contains busbars, disconnectors, circuit breakers, current transformers, bushing and support insulators is divided by horizontal and vertical partitions into separate compartments. The compartment in which the circuit breaker with the current transformer is located and the input (output) and busbar compartments located above it, with busbars, disconnectors, earthing switches, bushing insulators, is separated by a horizontal partition. In this partition, the axis of the disconnectors with the angular movement of the current-carrying knives and the current-carrying knives themselves in the disconnected position of the disconnectors are installed.

The control compartment, in which the actuators of the switches and disconnectors are located, is separated by partitions from the input (output) compartments, the busbar compartment and the compartment with the switch and current transformer.

The figure 1 shows the module in the operating position (switch and disconnector in the on position). The figure 2 presents the module in the repair position.

The closed-type high-voltage transformer substation module contains busbars 1 located in the building, electrically connected through a disconnector 2 with a switch 3, a current transformer 4, a disconnector 5 and through a bushing 6 with a current output 7. The module is divided into 8 separate horizontal compartments by 8 and vertical 9 partitions. A circuit breaker 3 with a current transformer 4 is located in compartment 10. Input and output compartments 11 and busbars 12 are located above compartment 10. Busbars 1, disconnectors 2 and 5, earthing switches 13 and 14, bushing insulators 6 are installed there. Compartment 10 is separated horizontal partition 8 from compartments 11 and 12. In this partition 8, the axis 15 of the disconnectors 2 and 5 with the angular movement of the current-carrying knives 16 are installed.

The control compartment 17, in which the actuators 18 of the switches 3 and the disconnectors 2 and 5 are located, is separated by partitions 8 and 9 from the input / output compartments 11, the busbar compartment 12 and the compartment 10.

When carrying out repair and maintenance work, the circuit breaker 3 and the disconnectors 2 and 5 are disconnected from the compartment 17. At the same time, the current-carrying knives 16 are rotated on the axes 15 and placed in niches made in horizontal partitions 8.

During repair and preventive maintenance, workers are protected from live parts by a high voltage horizontal partition, this allows not to disconnect the entire module.

All drive circuit breaker, grounding, disconnectors are located in the control compartment and are fully accessible for maintenance and management in any position of the equipment. The control compartment may have thermal protection and heating for ease of maintenance.
