Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, and in particular to a sealed pole with a voltage sensor integrated therein. Background Art

[0002] The sealed pole is a connection device in the vacuum circuit breaker, which is responsible for leading the current out of the vacuum chamber and connecting it to the external circuit. The main characteristics of the sealed pole are high-voltage insulation performance and good mechanical strength, and can withstand large mechanical stress and voltage stress. At the same time, it has good electrical conductivity and thermal stability, enabling it to work stably in high temperature and high pressure environments.

[0003] Outdoor high-voltage vacuum circuit breakers or load switches with ground fault protection function play an increasingly important role in the intelligent construction of modern distribution networks. Their main function is to quickly cut off the fault circuit when a ground fault occurs in the system, protect equipment and personal safety, and ensure the stable operation of the power system.

[0004] In order to ensure the stability of the equipment, people often hope to configure a voltage sensor in the sealed pole, but in the prior art, the voltage sensor is directly built into the base, such as the utility model patent No. 201220180514.6, which discloses a sealed pole with a built-in voltage sensor, including a silicone rubber layer, a vacuum arc chamber, an epoxy resin layer, an arc chamber tray, and an outgoing conductive block, characterized in that it also includes an incoming line voltage sensor and an outgoing line voltage sensor, the incoming line part of the vacuum arc chamber is connected to the incoming line voltage sensor, and the outgoing line of the vacuum arc chamber is connected to the incoming line voltage sensor. The outgoing voltage sensor is partially connected and then connected to the outgoing conductive block; the vacuum interrupter, the incoming voltage sensor, the outgoing voltage sensor and the outgoing conductive block are sealed with epoxy resin to form an epoxy resin layer, and a silicone rubber layer is also provided on the outer surface of the epoxy resin layer to form an integral pole; however, this structure is relatively simple, and the voltage sensor is directly configured in the matrix without constraints. It is difficult to ensure its position during manufacturing, and it is easy to move, and the arrangement of the wires is easy to shift. Based on this, it is necessary to study a sealed pole with an integrated voltage sensor. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a sealed pole with a voltage sensor integrated inside, which effectively solves the problems of the existing sealed pole being difficult to manufacture when configuring the voltage sensor, the voltage sensor lacking necessary installation points, and the voltage sensor and its wires being easily displaced.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a sealed pole with a voltage sensor integrated inside, comprising a base, a vacuum arc chamber, an insulating rod, a support seat, a first voltage sensor and a second voltage sensor; a support seat is provided in the middle of the base, an upper groove is provided on the upper part of the support seat, and a mounting seat is provided on the outer side thereof, a center hole is provided in the middle part, the lower part of the vacuum arc chamber is adapted to be mounted in the upper groove, the upper end of the insulating rod passes through the center hole and is connected to the lower end of the vacuum arc chamber, and the first voltage sensor and the second voltage sensor are symmetrically assembled on the mounting seat; the bottom of the vacuum arc chamber is connected to an outgoing line terminal, and the upper part thereof is connected to an incoming line terminal; the terminals of the first voltage sensor and the second voltage sensor are respectively connected to the outgoing line terminal and the incoming line terminal, and the other terminals of the two voltage sensors are respectively connected to the corresponding terminals via wires.

[0007] Furthermore, the substrate is an epoxy resin structure, and an insulating shell is arranged on the outside thereof.

[0008] Furthermore, the support seat and the mounting seat are an integral component supported by insulating material.

[0009] Furthermore, the mounting seats are arranged on both sides of the supporting seat and are provided with mounting grooves thereon, and the first voltage sensor and the second voltage sensor are adapted and fixed in the mounting grooves.

[0010] Furthermore, the wiring terminal is fixed with a wire tube, and the wire is arranged in the wire tube.

[0011] The beneficial effect of the above technical solution is that the utility model is structurally configured with a support seat structure, which can adaptively support the vacuum arc chamber from the bottom, and also serves as an installation base for the voltage sensor, thereby providing a fixed foundation for the installation of the voltage sensor, which can stably ensure the installation position of the voltage sensor and improve the balance, structural stability and production standardization of the structure.

[0012] In terms of structure, the utility model uses the built-in first voltage sensor and second voltage sensor to enable the sealed pole to detect and feedback the voltage status of the incoming and outgoing line terminals in real time. This real-time monitoring function can ensure the stable operation of the power system, detect voltage anomalies in time, and thus prevent possible failures. The built-in configuration of voltage sensors reduces external wiring and connection points, and reduces the risk of electrical failures caused by improper wiring or aging.

[0013] The support and mounting base are made of an integral component supported by insulating materials, which is simple and compact in design and easy to install and disassemble. In addition, the voltage sensor is adapted and fixed in the mounting groove, making the installation and replacement of the sensor more convenient and reducing maintenance costs.

[0014] Therefore, the utility model has two built-in voltage sensors in its structure, and the overall structural profile is a complete integrated sealed pole with high integration, small size and easy assembly. It not only improves the safety and reliability of the power system, but also optimizes the installation and maintenance process of the equipment, which is of great significance for improving the overall operating efficiency of the power system.

[0018] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods:

[0019] Embodiment 1, this embodiment aims to provide a sealed pole with a voltage sensor integrated inside, which is mainly used for sealed poles. As an important component in the power system, the sealed pole is mainly used to control the on and off of the circuit. However, the traditional sealed pole has shortcomings in voltage detection, and it is impossible to feedback the voltage status of the input and output line terminals in real time and accurately, resulting in potential risks in the operation of the power system. At the same time, the voltage detection method of the traditional sealed pole is mostly an external sensor. This method not only increases the wiring and connection points, increases the risk of electrical failure, but also increases the installation and maintenance costs of the equipment. Although the voltage sensor can be built into the sealed pole in the prior art, this kind of sealed pole is troublesome to manufacture when configuring the voltage sensor, the voltage sensor lacks the necessary installation points, and the voltage sensor and its wires are prone to displacement. This embodiment provides a sealed pole with a voltage sensor integrated inside.

The purpose of this embodiment is to embed the first voltage sensor 6 and the second voltage sensor 7 into the base 1. By embedding the first voltage sensor 6 and the second voltage sensor 7, the sealed pole can detect and feedback the voltage status of the incoming and outgoing line terminals in real time, ensure the stable operation of the power system, detect voltage anomalies in time, and prevent possible failures.

[0021] In order to achieve this purpose, in this embodiment, a support seat 4 is provided in the middle of the base 1, an upper groove is provided on the upper part of the support seat 4, and a mounting seat is provided on the outer side thereof, and a center hole is provided in the middle thereof. During implementation, the support seat 4 and the mounting seat are an integral component supported by insulating material. The design of the support seat 4 and the mounting seat makes the entire sealed pole structure stable, easy to install and maintain, reduces maintenance costs, and has a simple and compact design, which is easy to install and disassemble.

[0022] In terms of assembly relationship, the lower adapter of the vacuum arc chamber 2 is card-mounted in the upper card slot, the upper end of the insulating pull rod 3 passes through the center hole 41 and is connected to the lower end of the vacuum arc chamber 2, and the first voltage sensor 6 and the second voltage sensor 7 are symmetrically assembled on the mounting seat; this embodiment utilizes the support seat 4 to establish an adapter card-mounting relationship with the vacuum arc chamber 2, and configures the mounting seat based on the support seat 4, providing a basis for the installation of the voltage sensor.

[0023] In a further implementation structure, the mounting seats are arranged on both sides of the support seat 4, and are provided with mounting grooves 42. The first voltage sensor 6 and the second voltage sensor 7 are adapted and fixed in the mounting grooves 42. The mounting groove structure can improve the assembly firmness of the voltage sensor, making the installation and replacement of the sensor more convenient and reducing the maintenance cost.

[0024] In terms of specific wiring, the bottom of the vacuum arc chamber 2 is connected to the outgoing line terminal, and the upper part is connected to the incoming line terminal; the terminals of the first voltage sensor 6 and the second voltage sensor 7 are respectively connected to the outgoing line terminal and the incoming line terminal, and the other terminals of the two voltage sensors are respectively connected to the corresponding terminal blocks 10 via wires 8. The terminal blocks 10 are fixed with wire tubes 9, and the wires 8 are arranged in the wire tubes 9. The wire tube design of the terminal blocks 10 protects the wires and makes the wire layout neat and orderly for easy management.

[0025] The present embodiment has two built-in voltage sensors in the structure, and the overall structural profile is a complete integrated sealed pole with high integration, small size and easy assembly, which not only improves the safety and reliability of the power system, but also optimizes the installation and maintenance process of the equipment. At the same time, the support seat 4 structure can strengthen the connection between the vacuum arc chamber 2 and the collective, and also serves as the installation basis of the voltage sensor, thereby providing a fixed basis for the installation of the voltage sensor, which can stably ensure the installation position of the voltage sensor, improve the balance of the structure, structural stability and production standardization, and is of great significance to improving the overall operation efficiency of the power system.

[0026] The above-mentioned implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. The basic concept of the utility model is to provide an installation basis through the 4-position built-in voltage sensor of the support seat, thereby improving the safety and reliability of the power system.
