Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical technology, specifically to an intelligent measuring switch. Background Technology

[0002] Intelligent metering switches are the intelligent "controllers" of energy information flow and business flow. As a key component of low-voltage distribution areas, they are directly related to the safe, intelligent, and economical use of electricity by a large number of power users, and have significant social and economic value.

[0003] With the development of intelligent measurement switches, more and more electronic components are integrated on the switch body. The lifespan of these electronic components is 3 to 8 years, while the lifespan of the intelligent measurement switch body is 12 to 16 years. The lifespan of the electronic components and the intelligent measurement switch body differs greatly. Currently, most intelligent measurement switches adopt an integrated design, that is, the functional components of the intelligent measurement switch body and its integrated electronic components are integrated into one unit. If any electronic component is damaged, the entire intelligent measurement switch needs to be replaced, which is costly.

[0004] However, a modular design would require more space for installation. The challenge lies in accommodating more functional modules while keeping the size of the measurement switch unchanged. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an intelligent measurement switch.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A smart measuring switch, comprising:

[0008] A first housing, wherein the interior of the first housing is configured along the length of the first housing as a first region and a second region for mounting a single-phase operating mechanism;

[0009] Several single-phase operating mechanisms are disposed in the first area and arranged side by side along the width direction of the first housing;

[0010] At least one circuit board is disposed in the second area and has several interfaces;

[0011] Several functional modules are arranged side by side along the width of the first housing and are pluggably connected to the interface of the circuit board.

[0012] The functional modules include an electricity meter module, a carrier wave module, an electronic protection module, and a power supply module.

[0013] The circuit board is fixedly mounted inside the first housing by a mounting bracket.

[0014] The bottom of the mounting base is provided with several positioning grooves distributed along the width direction of the first housing.

[0015] The bottom of the mounting base is also provided with several baffles distributed along the width direction of the first housing.

[0016] The functional module includes a second housing and a functional circuit board located within the second housing.

[0017] The first housing includes a base and a top cover, the top cover having a window for accommodating functional modules.

[0018] The window is equipped with an openable cover.

[0019] The second housing has grooves at both ends.

[0020] The beneficial effects of this utility model are as follows: This application divides the housing into two areas, one area for accommodating the single-phase operating mechanism and the other area for arranging functional modules side by side. The functional modules are pluggable, making maintenance and replacement more convenient. At the same time, the distribution along the width direction greatly reduces the length of the measuring switch, allowing more functional modules to be accommodated within a standard size.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] like Figure 1 As shown, this utility model discloses an intelligent measuring switch, which includes a first housing 100. The first housing 100 includes a base 110 and a top cover 120. The top cover 120 is provided with a window for accommodating a functional module. An openable cover plate 111 is provided at the window.

[0030] See Figure 4 The first housing is divided into several phase wire channels 123. The two ends of the first housing are the inlet and outlet terminals, respectively. Each phase wire channel is set independently. At the same time, the first housing is divided into multiple connected spaces by several partition plates set along its length.

[0031] A first housing 100 has a first region 121 and a second region 122 arranged along the length of the first housing 100 for mounting a single-phase operating mechanism, and the first region and the second region are in contact with each other.

[0032] A plurality of single-phase operating mechanisms 700 are disposed within the first region 121 and arranged side-by-side along the width direction of the first housing 100. Each single-phase operating mechanism 700 is used to electrically connect to an external line, which includes three phases: A, B, and C. The multiple single-phase operating mechanisms 700 are housed within the base, and each single-phase operating mechanism 700 can close or open to control the connection or disconnection of one phase of the external line. For example, the multiple single-phase operating mechanisms are spaced apart along the width direction of the first housing. Figure 4 In this diagram, the Y direction represents the width, and the X direction represents the length.

[0033] like Figure 3 As shown, at least one circuit board 610 is disposed in the second area 122 and has several interfaces. The circuit board 610 is used as an adapter board to output the data of each detection module in the measurement switch to the corresponding functional module via the circuit board. At the same time, the power supply module supplies power to each functional module via the circuit board.

[0034] See Figure 2Several functional modules are arranged side by side along the width direction of the first housing 100 and are pluggably connected to the interface of the circuit board 610. The length of each functional module is uniform. According to the size of the functional circuit board of different functional modules, the second housing with different widths is set, so that all functional modules are arranged side by side, making the whole more neat. At the same time, the width can be adjusted to meet the overall width limit.

[0035] Meanwhile, the functional modules include a meter module 200, a carrier module 300, an electronic protection module 400, and a power supply module 500. The four functional modules are arranged in sequence and do not interfere with each other. They are directly connected to the circuit board 610 through an interface to realize data transmission.

[0036] The second area of ​​the base 110 is used to install a terminal block. Multiple detection modules, such as metering transformers 10, current transformers 20, and leakage current transformers 30, are mounted on the terminal block, utilizing the bottom space of the base. A flux mounting base (not shown in the figure) is installed above the metering transformer 10, and a flux trip unit is installed within the flux mounting base. The number of flux trip units can be the same as the number of single-phase operating mechanisms. When a short circuit occurs in the phase corresponding to the flux trip unit, the flux trip unit can cause the single-phase operating mechanism to trip. This solution is a conventional technical method and therefore will not be described in detail.

[0037] In this embodiment, three single-phase operating mechanisms and three magnetic flux trip devices are provided, each corresponding to one of the three phase lines of the external line, thereby realizing the independent disconnection of the three phase lines of the external line.

[0038] A mounting base is provided on the upper end of the current transformer and the leakage current transformer. The circuit board 610 is fixedly mounted in the first housing 100 by the mounting base 600. The mounting base has a cavity for accommodating the components of the circuit board. Preferably, one end of the mounting base extends above the flux trip unit, thereby covering the entire flux mounting base and the flux trip unit. See [reference needed]. Figure 6 One end of the mounting base is divided by multiple partitions to form independent chambers 630, which are used to accommodate the flux trip device disposed on the flux mounting base.

[0039] The mounting base 600 has several positioning grooves 640 distributed along the width of the first housing 100 at its bottom. An intermediate wall is provided between each phase wire channel on the base, and a positioning reinforcing rib 124 is provided at the upper end of the intermediate wall. This rib cooperates with the positioning grooves to achieve a fixed connection between the mounting base and the base, while simultaneously improving electrical isolation between the phase wire channels through the interlocking fit.

[0040] The mounting base 600 is also provided with several baffles 620 distributed along the width of the first housing 100 at its bottom. A slot 125 is provided in the corresponding phase line channel. The slots are arranged opposite each other, forming a gap between them for the terminal block to pass through. Furthermore, this slot is located between the current transformer and the metering transformer. The design of inserting the baffles into the slots separates the phase line channels, ensuring that the current transformer and the metering transformer do not interfere with each other, thus improving detection accuracy.

[0041] The functional module includes a second housing and functional circuit boards inside the second housing. The circuit principle of each functional circuit board adopts conventional circuits, and the functional circuit boards are laid out according to the designed width so that they can be installed in the second housing of the corresponding width. Therefore, the functional circuit boards are not described in detail.

[0042] In this embodiment, the meter module has the largest size, while the widths of the carrier module 300, electronic protection module 400, and power supply module 500 decrease sequentially. This internal layered design can meet the layout requirements of different functional circuit boards.

[0043] The second housing has grooves 800 at both ends. The grooves are designed to allow fingers to be inserted into them for plugging and unplugging the functional module.

[0044] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
