Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage electrical appliance components, in particular to a heat dissipation type solid-sealed pole. Background Art

[0002] With the continuous expansion of the scale of power systems and the increasing requirements for power quality, high-voltage switchgear, especially sealed poles, as a vital component of high-voltage electrical appliances, has a direct impact on the safe and stable operation of the power system. The sealed poles are mainly responsible for the on-off function of high-voltage circuits, and their internal structure is complex, including but not limited to key components such as vacuum interrupters, insulating supports, and conductive connectors.

[0003] In the prior art, the design of the outlet structure of the sealed pole usually focuses on the guarantee of electrical performance and mechanical strength, but pays insufficient attention to the heat dissipation problem at the connection. In particular, the connection between the upper end of the insulating pull rod and the flexible connection often generates a large amount of heat during operation due to the high current density and harsh working environment. If this part of the heat cannot be dissipated in a timely and effective manner, it will cause the local temperature to rise sharply, causing the performance of the insulation material to deteriorate, the metal parts to accelerate oxidation and even produce thermal fatigue. In severe cases, it may cause insulation breakdown, loose or broken connections, affecting the safety and reliability of the equipment.

[0004] Traditional heat dissipation methods mostly rely on the heat conduction and convection of the shell itself, but for high-power applications or long-term heavy-load conditions, these passive heat dissipation measures are often inadequate. In addition, due to the compact internal space of the sealed pole, adding additional active cooling devices (such as fans, cooling fans) is not only technically difficult to implement, but also increases the cost and complexity of the equipment.

[0005] In view of the above problems, the present application proposes a heat dissipation type solid-sealed pole. Utility Model Content

[0006] In view of the deficiencies in the background technology, the utility model provides a heat dissipation type solid-sealed pole.

[0007] The technical solution adopted by the utility model is: a heat-dissipating solid-sealed pole, comprising a shell, a first wire outlet is provided on the top of the shell, a second wire outlet is provided on the side of the shell, a wiring expansion is provided on the inner side of the shell located at the second wire outlet, a heat dissipation block is provided in the shell of the outer circle of the wiring expansion, and a ventilation hole connected to the outside of the shell is provided on the shell of the outer circle of the heat dissipation block.

[0008] Furthermore, a cover groove is provided on the shell outside the ventilation hole, and the cover groove is covered with dustproof cotton.

[0009] Furthermore, a dust-proof umbrella skirt is provided on the shell above the cover groove.

[0010] Furthermore, the dust shield skirt is arranged to be tilted downward.

[0011] Furthermore, the heat dissipation block is a circular structure, and a clearance gap is provided on one side thereof.

[0012] Furthermore, a voltage measuring coil and a current measuring coil are provided on the outer ring of the second wire outlet.

[0013] Furthermore, a connection step with a dovetail structure is provided on the surface of the heat dissipation block.

[0014] The beneficial effects of the utility model are:

[0015] 1. Significantly improve heat dissipation efficiency: This application sets a wiring expansion port on the inner side of the second outlet shell, and a built-in heat dissipation block near the wiring expansion port, directly targeting the key heat source of the upper end of the insulating pull rod and the soft connection. The heat dissipation block uses its high thermal conductivity to effectively absorb and conduct heat, and combined with the external ventilation hole design, it forms an effective heat exchange channel, which significantly accelerates the dissipation of heat energy, effectively avoids local overheating, and improves the working stability and safety of the entire sealed pole.

[0016] 2. Enhance the reliability of electrical equipment: Through optimized heat dissipation design, the temperature of the connection parts is effectively controlled, reducing the problems of aging of insulation materials and oxidation and rusting of metal parts caused by high temperature, thereby extending the service life of the sealed poles and related electrical components, and improving the operating reliability and maintenance cycle of the entire power system.

[0017] 3. Innovative structural design: The introduction of wiring expansion increases the ventilation space at the connection, and by improving the heat dissipation performance, reduces the failure rate caused by overheating, thereby reducing the maintenance frequency and maintenance costs. At the same time, this design does not require major changes to the overall structure, and is easy to promote and implement directly in existing equipment, with high practical value and economic benefits.

[0018] 4. Strong environmental adaptability: The optimized heat dissipation system improves the adaptability of the sealed pole to extreme working environments, especially under harsh conditions of high temperature, high humidity or high dust, which can effectively ensure the normal operation of the equipment and broaden its application scope.

If the specific posture changes, the directional indication will also change accordingly.

[0026] The utility model provides a heat dissipation type solid-sealed pole.

[0027] In this embodiment, refer to Figure 1-2 The heat dissipation type sealed pole comprises a shell 1, a first wire outlet 2 is arranged on the top of the shell 1, a second wire outlet 3 is arranged on the side of the shell, a wiring expansion opening 4 is arranged on the inner side of the shell located at the second wire outlet, a heat dissipation block 5 is arranged in the shell of the outer circle of the wiring expansion opening, and a ventilation hole 6 connected to the outside of the shell is arranged on the shell of the outer circle of the heat dissipation block.

[0028] In the above technical solution, by setting a wiring expansion port inside the second outlet shell and a built-in heat sink, thermal management is directly performed on the key heating area, significantly improving the heat dissipation efficiency of the connection, effectively avoiding problems such as insulation performance degradation and metal component oxidation caused by local overheating, thereby enhancing the stability and service life of the sealed pole. The setting of the ventilation holes promotes air circulation inside and outside the shell, further accelerates the dissipation of heat, and improves the overall heat dissipation performance.

[0036] Specifically, a voltage measuring coil 11 and a current measuring coil 12 are provided on the outer ring of the second outlet.

[0037] By adding voltage measuring coils and current measuring coils to the outer ring of the second outlet, real-time monitoring of current and voltage can be achieved directly on the sealed pole without the need for additional sensor installation, which simplifies the monitoring system and improves the automation level of the power system and the safety of operation.

[0038] Specifically, a connection step 13 of a dovetail structure is provided on the surface of the heat dissipation block.
