Description

Technical Field

[0001] The present invention relates to the technical field of power generation, transformation or distribution. Specifically, it relates to a primary-secondary deeply integrated distributed power distribution terminal device and its usage method. Background Art

[0002] Based on the development concept of the primary-secondary deeply integrated ring main unit, considering the need for the integration of the terminal and primary equipment, the substation terminal is installed dispersedly inside the primary equipment. Standardizing the design of the distributed substation terminal and stipulating the functions, performance, interfaces, structures, and supporting equipment of the terminal is a trend.

[0003] After retrieval, in the prior art, a Chinese patent with the patent application number CN202122646316.6 discloses a primary-secondary deeply integrated distributed power distribution terminal device, belonging to the technical field of power generation, transformation or distribution. This device is applied to the distribution ring main unit, and the substation terminal is installed dispersedly inside the primary equipment. This device standardizes the design of the distributed substation terminal. The operation panel on the front panel integrates indicator lights, a liquid crystal display module, operation buttons, hard pressure plates, opening and closing buttons, and a mode selection knob. A rectangular connector is installed on the back panel, and there is a first network port for receiving the PPS signal output by the common unit and a second network port for sending the PPS signal to another power distribution terminal device. The mode selection knob includes a knob for selecting remote operation or local operation and a knob for selecting protection functions, intelligent distribution, and voltage-current type, having the advantages of miniaturization, easy installation, plug-and-play, durability, and high IP protection, but still has the following defects:

[0004] (1) In the prior art, the operation panel of the power distribution terminal is installed inside it. When the internal components of the operation panel are damaged, it is inconvenient for maintenance personnel to repair, and the maintenance space is small, resulting in a greater difficulty in maintenance.

[0005] (2) In the prior art, the power distribution terminal has a sealed structure. During long-term use, a large amount of heat will accumulate inside it, making it inconvenient to dissipate heat from the power distribution terminal device. The accumulation of heat inside it is likely to accelerate the aging speed of internal components and reduce the service life.

[0060] Specifically, when the primary-secondary deep integration distributed power distribution terminal device is working / being used: corresponding components are connected through the indicator light 4, the operation display module 5, the hard pressure plate 6, the opening and closing buttons 7, the mode selection knob 8 and the rectangular connector 14, and corresponding modes are selected for use; when maintenance or repair of the terminal is required, the handwheel 1010 is rotated to drive the transmission rod 1008 and the worm 1009 to rotate. The rotation of the worm 1009 drives the worm gear 1007, the transmission shaft 1005 and the driving bevel gear 1006 to rotate synchronously. The driving bevel gear 1006 drives the driven bevel gear 1004 and the threaded rod 1002 to rotate.

After the repair is completed, the carrier plate 2 is retracted. When the movable block 1102 contacts the limit opening 1111, the movable block 1102 rotates, and then the support legs 1105 are folded and retracted, so as to support the outwardly moved carrier plate 2 and ensure stability; when heat dissipation is required, the motor 1618 is started to rotate the reciprocating lead screw 1605. The rotation of the reciprocating lead screw 1605 drives the moving rod 1606 to move up and down reciprocally, so that the fan blade 1609 rotates. At the same time, the rotation of the reciprocating lead screw 1605 drives the first bevel gear 1614 thereon to rotate, and then through the transmission of the second bevel gear 1617 and the assembly shaft 1616, the spline shaft 1613 rotates.
