Abstract

The utility model discloses a parallel arrangement structure of two sets of DC filters in an ultra-high voltage converter station, which relates to the technical field of electric power engineering. The purpose of the invention of the utility model is to provide an arrangement method of parallel connection of two sets of DC filters in the UHV converter station which can reduce the high and low voltage side circuit equipment and fences of the filter, thereby saving investment and land occupation. The technical scheme adopted by the utility model is as follows: the positive and negative poles of the converter station are respectively equipped with two sets of DC filters; and the two sets of DC filters at any pole of the converter station are arranged in parallel; The filter is arranged in the same fence, and only shared circuit equipment is arranged on the high and low voltage sides.

Description

The arrangement of two groups of DC filter parallel connections of a kind of ultra-high voltage converter station

Technical field

The utility model relates to electric power project engineering field, relates in particular to the arrangement of ultra-high voltage converter station DC filter parallel connection.

Background technology

In current conversion station in the past, in the time that negative or positive electrode is installed two groups of DC filter, adopt completely independently arrangement of two groups of filters, every group of filter branches is arranged in separately independently in fence, the independent loop equipment such as high and low pressure side isolating switch and earthed switch of arranging.

Current conversion station is stood entirely needs 4 groups of DC filter of installing, correspondingly, need to arrange 4 loop, cover high-pressure side equipment, 4 cover low-pressure side loop equipment and 4 fences.Equipment investment is larger, meanwhile, arranges that a large amount of high pressure and low tension loop equipment also can take up an area more.

Utility model content

Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide the arrangement of two groups of DC filter parallel connections of a kind of ultra-high voltage converter station.

The technical solution adopted in the utility model is such: the positive pole of current conversion station and negative pole configure respectively two groups of DC filter; And after two groups of DC filter parallel connections of any utmost point of current conversion station, two groups of DC filter are arranged in same fence.

Preferably, at any utmost point of current conversion station:

The high-pressure side parallel connection of two groups of DC filter is later by being arranged in the common high voltage loop equipment access polar curve outside fence;

The low-pressure side parallel connection of two groups of DC filter is later by being arranged in the shared low tension loop equipment access neutral line outside fence.

In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:

Two groups of DC filter are arranged in parallel, and share the equipment outside fence and fence, and two groups of filters only need 1 cover high tension loop equipment, 1 cover low tension loop equipment and 1 cover fence, and saving equipment and fence quantity, save and take up an area and investment.

Accompanying drawing explanation

Fig. 1 is the layout schematic diagram of a specific embodiment of the utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 1, in a specific embodiment of the present utility model, all dispose two groups of DC filter at positive pole and the negative pole of current conversion station; At any utmost point:

Two groups of DC filter parallel connections are arranged in same fence later.

The equipment such as the capacitor of the DC filter in fence, reactor, resistor adopt low level support arrangement, and wherein high-voltage capacitance adopts three tower brace types to arrange.

After the high-pressure side parallel connection of two groups of DC filter, by being arranged in the common high voltage loop equipment access polar curve outside fence.

After the low-pressure side parallel connection of two groups of DC filter, by being arranged in the shared low tension loop equipment access neutral line outside fence.

The equipment room of high tension loop and low tension loop inside connects by flexible conductor or hard conductor.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.

Claims
