The energy-taking CT protection device can effectively meet the requirements of water resistance, stability and insulation on the energy-taking CT protection device through assembly with the energy-taking CT so as to ensure safe and effective operation of the dry-type reactor turn-to-turn short circuit on-line monitoring device.

Description

Energy-taking CT protection device

Technical Field

The utility model belongs to the technical field of substation equipment maintains, concretely relates to get ability CT protection device.

Background

Because the dry-type reactor is not shielded by a shell, and large potential difference exists between phases and phases of the coil, the conventional method for acquiring energy and supplying power cannot be adopted for the on-line monitoring of the dry-type reactor installed at present.

The self-energy-taking CT device has the function of realizing the transfer of partial electric energy from a lead to an induction power supply module through the isolation and transformation of current, and the design of the self-energy-taking CT device needs to comprehensively consider various factors such as wake-up current, minimum working current, output power, installation structure size, short-time withstand current and the like. The energy-taking CT needs to be installed on a lead, the lead is used as a primary coil, and the CT is used as a secondary coil. Because the existing lead cannot be disassembled during installation, the energy-taking CT needs to be made into two identical semicircular shapes and combined into an integral circle during installation. Therefore, the energy-taking CT does not have a good protection grade and cannot be directly used outdoors.

SUMMERY OF THE UTILITY MODEL

To the deficiency in the prior art, the present disclosure aims to provide an energy-taking CT protection device, including: the device comprises a device body and a meniscus, wherein the device body is annular and is formed by splicing at least 2 semicircular rib plates; the meniscus and the upper end face and the lower end face of the semicircular rib plate are provided with threaded holes, and the meniscus is connected with the semicircular rib plate through bolts.

Preferably, the upper end face of the semicircular rib plate is connected with 2 menisci, the lower end face of the semicircular rib plate is connected with 2 menisci, and the spliced menisci and the device body form a closed cavity.

Preferably, the meniscus is provided with a groove.

Compared with the prior art, the beneficial effect that this disclosure brought does: the energy-taking CT protection device can effectively meet the requirements of water resistance, stability and insulation on the energy-taking CT protection device through assembly with the energy-taking CT so as to ensure safe and effective operation of the dry-type reactor turn-to-turn short circuit on-line monitoring device.

Detailed Description

Specific embodiments of the present disclosure will be described in detail below with reference to fig. 1. While specific embodiments of the disclosure are shown in the drawings, it should be understood that the disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

It should be noted that certain terms are used throughout the description and claims to refer to particular components. As one skilled in the art will appreciate, various names may be used to refer to a component. This specification and claims do not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. The description which follows is a preferred embodiment of the invention, but is made for the purpose of illustrating the general principles of the invention and not for the purpose of limiting the scope of the invention. The scope of the present disclosure is to be determined by the terms of the appended claims.

To facilitate an understanding of the embodiments of the present disclosure, the following detailed description is to be considered in conjunction with the accompanying drawings, and the drawings are not to be construed as limiting the embodiments of the present disclosure.

In one embodiment, as shown in fig. 1, the present disclosure provides an energy-extracting CT protection device, including: the device comprises a device body and a meniscus, wherein the device body is annular and is formed by splicing at least 2 semicircular rib plates; the meniscus and the upper end face and the lower end face of the semicircular rib plate are provided with threaded holes, and the meniscus is connected with the semicircular rib plate through bolts.

In this embodiment, connect semicircle rib plate and meniscus through the screw and constitute airtight space, will get can CT and arrange in this space, can satisfy waterproof, firm and insulating requirement to getting can CT. In addition, because the meniscus is removable, the energy-extracting CT can be freely removed from the protective device.

In another embodiment, the upper end face of the semicircular rib plate is connected with 2 menisci, the lower end face of the semicircular rib plate is connected with 2 menisci, and the menisci and the device body form a closed cavity after being spliced.

In this embodiment, through the concatenation meniscus, can form airtight space with the device body, will get can CT and place in this airtight space, can effectually protect getting can CT, but consider to get can CT and need supply power to external equipment through the lead wire, consequently, need leave the space between the meniscus of 2 concatenations, be convenient for draw forth the lead wire.

In another embodiment, the meniscus is fluted.

In this embodiment, after the energy-taking CT is installed on the reactor block, the device is sleeved on the energy-taking CT and coaxial therewith, and the device is matched with the aluminum block through the groove on the meniscus.

The above embodiments are further intended to illustrate the objects, technical solutions and advantages of the present disclosure, and it should be understood that the above embodiments are only preferred embodiments of the present disclosure, and should not be construed as limiting the present disclosure, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present disclosure should be included in the scope of the present disclosure.
