Description

Stationary metal switchgear

Technical Field

The utility model relates to a technical field of regulator cubicle, in particular to fixed metal switchgear.

Background

The ring main unit is widely used without long time, mainly because newly developed buildings of industrial enterprises and public institutions use medium and small-sized capacity as most of distribution transformers of the ring main unit generally not more than 1250KVA from the perspective of power supply and distribution, and can stably supply power for a long time, and a high-voltage switch is not frequently operated. For such users, the performance of the ring main unit is not perfect, but is sufficient. With large-scale urban construction, a large number of large-scale high-rise buildings are pulled out, the power transformation and distribution substation is often arranged below a building, the power transformation and distribution equipment must be oilless according to the fire protection requirement, the power transformation and distribution equipment should be miniaturized according to reasonable use of construction area, and then a ring main unit or a vacuum circuit breaker, a dry transformer and a dry transformer enter the building. However, most of the existing ring main units have the problems of complex structure, high production cost, poor environmental adaptability, no monitoring of the leakage condition of the filled SF6 gas, potential safety hazard and the like.

According to the scheme, personnel can only open the cabinet door through the electronic lock; the arrangement of the embedded strip and the groove increases the sealing performance of the opening and closing position between the cabinet door and the cabinet body when the cabinet door is closed.

One preferred scheme is that a plurality of partition boards are arranged inside the cabinet body, the partition boards are detachably connected with the cabinet body, and the partition boards are provided with wire passing grooves.

According to the scheme, the partition plate can be detached from the cabinet body, so that the maintenance of personnel is facilitated; the cable passing groove is arranged to facilitate the cable to pass through and connect with other elements.

According to a preferable scheme, a base is arranged at the bottom of the cabinet body, and a shockproof pad is arranged at the joint between the base and the cabinet body.

According to the scheme, the base is arranged, so that the cabinet body and the ground have a certain height, and the cabinet body is prevented from being in contact with the damp ground to cause damp corrosion; the arrangement of the shockproof pad reduces the shaking of the cabinet body and reduces the noise.

According to a preferred scheme, the four corners of the top of the cabinet body are provided with hanging ring mounting seats and hanging rings, one ends of the hanging ring mounting seats are fixedly connected with the upper end face of the cabinet body, the other ends of the hanging ring mounting seats are fixedly connected with the side end face of the cabinet body, and the hanging rings are hinged to the hanging ring mounting seats in a one-to-one correspondence mode.

According to the scheme, the lifting ring mounting seat is connected with the upper end face and the side end face, so that the lifting ring is higher in connection strength with the cabinet body, the lifting ring is convenient to carry, and the lifting ring is firmer and more stable in carrying.

One preferred scheme is that the cabinet body is provided with an emergency stop button and a protective cover which is hinged on the cabinet body and is matched with the emergency stop button.

According to the scheme, the protective cover is arranged to prevent the emergency stop button from being touched by mistake; the emergency stop button is arranged, so that the safety is improved.
