Problems solved by technology

Except for the handcart switch (circuit breaker mechanism) of this switchgear, which can be moved and pulled out for maintenance, other accessories are fixed. If it is for normal annual maintenance or fault maintenance, the required power outage will last for a long time (about 8 hours), and the power outage time will be longer if there are no accessories. long, which greatly affects the normal use

Embodiment 1

[0042] Such as Figure 1-Figure 3 As shown, a high-voltage switchgear system is composed of two adjacent high-voltage switchgears fixedly connected by bus bar 20 and incoming copper bar 10. The bus bar 20 is vertically drawn out from the main bus bar in a "T" shape. , the incoming copper bar 10 of the high-voltage switchgear has a rectangular section, and the corresponding busbar copper bar 20 is a concave section guide rail for the incoming line copper bar 10 to insert, and the ends of the two wings of the concave section guide rail are bent inward 90° to form a bent portion 22 (the concave shape of the busbar copper bar 20 and the bent portion 22 constitute the placement space for the incoming copper bar 10 after insertion); the busbar copper bar 20 and the incoming copper bar 10 are each provided Two bolt holes 30, the bolt holes 30 on the two copper bars are connected to form two integrally penetrated bolt holes 30 after the two copper bars are fully inserted; One side of...

Embodiment 2

[0051] Such as Figure 4 As shown, this embodiment optimizes the structure of the busbar copper bar 20 on the basis of Embodiment 1. Specifically, the guide rail of the bus bar copper bar 20 is a telescopic sleeve guide rail, and is provided with a fixing button 21, and the fixing button 21 is the plug-in bearing pin. Through the above design, when the electric wrench 40 fails to unscrew the bolt 42, the fixing of the copper bar can be manually released, so that the disassembly of the copper bar has double guarantees, and the safety and flexibility are improved. Specifically, the power supply is disconnected, the fixing button 21 is removed, the busbar copper bar 20 and the incoming line copper bar 10 are pulled out through the telescopic sleeve guide rail, and the bolt 42 is manually unscrewed.

Embodiment 3

[0053] Such as Figure 5 As shown, this embodiment optimizes the structure of the high-voltage switchgear cabinet on the basis of Embodiment 2, specifically: the two sides of the high-voltage switchgear cabinet are respectively provided with positioning benchmarks 50 and positioning holes 51 opposite to it , the positioning benchmark 50 is slidably arranged in the pipeline of the high-voltage switchgear cabinet. After the high-voltage switchgear is installed, the end of the positioning benchmark 50 is inserted into the special cabinet positioning hole 51 of the switch cabinet, and is fixed by a positioning locking device.

[0054] In this embodiment, through the design of the positioning pole 50 and the positioning hole 51, the high-voltage switchgear can quickly correspond to the cabinet body during installation, without using external scales or tools, which is convenient for quick installation; the positioning locking device improves the overall connection of the cabinet body...

Abstract

The invention discloses a high-voltage switchgear system that can quickly replace the high-voltage switchgear when it is installed or encounters a fault, and belongs to the technical field of switchgear; It is a concave cross-section guide rail for the insertion of incoming copper bars, and the ends of both sides of the concave cross-section guide rail are bent inward to form a bent part; the bus bar and the incoming copper bar are each provided with at least two bolts The bolt holes of the two copper bars are connected after plugging; the cabinet body where the bus bar is located is provided with an electric wrench corresponding to the position of the bolt hole on the side of the connected bolt hole; the electric wrench is placed on a fixed On the support sleeve, the working end is connected with a bolt facing the bolt hole, and the free end is connected with a compression spring. The top of the electric wrench is fixedly connected with an operating handle that goes out of the high-voltage switch cabinet. The top of the high-voltage switch cabinet is provided with a Channel for the reciprocating movement of the operating handle.

Description

technical field [0001] The invention relates to the technical field of switchgears, in particular to a high-voltage switchgear system and a high-voltage switchgear replacement method that can be quickly replaced as a whole when the high-voltage switchgear fails, and the connection between the cabinets is fast and reliable. Background technique [0002] High-voltage switchgear refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. High-voltage switchgear is used as electrical products with a voltage level of 3.6kV ~ 550kV, high-voltage isolating switch and grounding switch, high-voltage load switch, high-voltage automatic reclosing and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear. category. Among them, 10kV substation high-voltage switchgear is widely used. According to the structure type, it can b...
