Description

Technical Field

[0001] This utility model relates to the field of measuring sleeve technology, specifically to the measuring sleeve for environmental protection cabinets. Background Technology

[0002] The installation of traditional metering bushings is more difficult and time-consuming, which not only reduces installation efficiency but may also affect bushing performance due to improper installation, thus reducing the ease of installation. From the perspective of the sources and effects of external electromagnetic interference, there are a large number of electromagnetic interference sources in the surrounding area. When interference signals enter the bushing, they will be superimposed on the normal metering signal, causing deviations in the metering device's detection. This will not only cause inaccurate metering data and affect the fairness of electricity metering, but may also interfere with the normal operation of the metering device, causing problems such as misjudgment and malfunction, threatening the stable operation of the power grid.

[0003] Utility model patent CN222775073U discloses a conductive component, a sleeve body sleeved outside the conductive component, and an insulating boss provided on the outer periphery of the sleeve body. A wiring port is provided on the sleeve body in its radial direction. This utility model facilitates production and wiring.

[0004] However, the device lacks a secure mounting mechanism and an internal shielding against external interference, resulting in insecure installation, which affects the performance of the bushing and makes it susceptible to external interference, leading to problems such as misjudgment and malfunction. Utility Model Content

[0007] As a preferred embodiment of this utility model, the mounting ring is installed around the bottom of the mounting sleeve, a lower fixing ring is installed at the bottom of the mounting ring, an inner fixing tube is passed through the center of the top surface of the lower fixing ring, and four fixing bolts are threaded around the mounting ring.

[0008] As a preferred embodiment of this utility model, the steel strip shielding layer is fixedly connected to the inside of the inner tube, and an inner shielding layer is installed inside the steel strip shielding layer.

[0009] As a preferred embodiment of this utility model, the inner shielding layer is made of epoxy resin, and an inner insulating sheath is fixedly connected inside the inner shielding layer.

[0010] As a preferred embodiment of this utility model, a sealing ring is installed on the top surface of the lower fixing ring, and the middle part of the sealing ring is sleeved on the outside of the inner fixing tube.

[0011] As a preferred embodiment of this utility model, the outer sleeve of the inner tube is fitted inside the bottom end of the inner sleeve, and the bottom of the inner tube is fixedly connected to an outer sleeve.

[0012] As a preferred embodiment of this utility model, the lower fixing ring is fixedly connected with threaded mounting ports on all four sides, and a sealing gasket is installed on the outside of the threaded mounting ports.

[0013] As a preferred embodiment of this utility model, the middle part of the sealing gasket is threaded to the outside of the fixing bolt, and the bottom surface of the sealing gasket is installed on the bottom surface of the inner sleeve.

[0014] Compared with the prior art, this utility model provides a metering sleeve for environmental protection cabinets, which has the following beneficial effects:

[0015] 1. The metering sleeve of this environmental protection cabinet, through the setting of the installation mechanism, when the device is to be used, first install the installation ring inside the outer cabinet, then align the outer sleeve with the inner installation ring on the outside, so that the inner fixing tube can pass through the outer cabinet and enter the inner sleeve. Then, use the fixing bolt to pass through the installation ring and the lower fixing ring to fix it, which plays a role in facilitating a firm installation and avoiding insufficient installation, which would affect the performance of the sleeve and reduce the convenience of installation.

[0016] 2. The metering sleeve of this environmental protection cabinet, through the setting of the shielding mechanism, has steel strip shielding layers installed inside both the inner and outer sleeves when the device is to be used, blocking some interference. Then, an inner shielding layer is installed inside the steel strip shielding layer. The inner shielding layer is made of epoxy resin. The multi-level shielding of external interference plays a role in shielding against external interference and avoids signal interference. This not only causes inaccurate metering data and affects the fairness of electricity metering, but may also interfere with the normal operation of the metering device. Attached Figure Description
