Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic grid-connected cabinets, and in particular to a photovoltaic grid-connected cabinet with a fool-proof wiring mechanism. Background Art
[0002] In a photovoltaic grid-connected cabinet, the direct current generated by the photovoltaic cells needs to be converted into alternating current through an inverter, and then injected into the grid. This requires the use of live wires and neutral wires. Generally, the live wire is connected to the output end of the inverter, and the neutral wire is connected to the neutral wire of the grid.
[0003] During the wiring and assembly of existing photovoltaic grid-connected cabinets, due to the large number of lines and high complexity, it is not conducive for power workers to quickly identify the assembly position of the lines, so reverse connection and wrong connection may occur. There is a lack of a set of fool-proof mechanisms that can help photovoltaic power workers in wiring.
[0004] The existing photovoltaic grid-connected cabinet wiring operation has the following disadvantages: During the wiring operation, the existing photovoltaic grid-connected cabinet has no fool-proof positioning mechanism for the connection line, which leads to complex early wiring, easily leading to increased risks of line assembly errors and reverse connection, and affecting the stability of the photovoltaic grid-connected cabinet. To this end, we propose a photovoltaic grid-connected cabinet with a fool-proof wiring mechanism. Utility Model Content
[0005] The main purpose of the utility model is to provide a photovoltaic grid-connected cabinet with a fool-proof wiring mechanism, which can effectively solve the problems in the background technology.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A photovoltaic grid-connected cabinet with an anti-mistake wiring mechanism comprises a photovoltaic grid-connected cabinet body, a support arm and a magnetic rubber strip, and also comprises a neutral line anti-mistake assembly and a live line anti-mistake assembly. The support arm is arranged in the photovoltaic grid-connected cabinet body, and both ends of the support arm are fixedly installed with the photovoltaic grid-connected cabinet body by bolts. A plurality of neutral line anti-mistake assemblies and live line anti-mistake assemblies are arranged, and the neutral line anti-mistake assemblies and live line anti-mistake assemblies are sequentially clamped along the support arm.
[0008] Furthermore, the neutral wire fool-proofing assembly and the live wire fool-proofing assembly both include a ferrule, b ferrule, a spring hinge and an L-shaped hook.
[0009] Furthermore, the L-shaped hook is integrally arranged on the back of the a sleeve, and the a sleeve is rotatably connected to one end of the b sleeve via a spring hinge.
[0010] Furthermore, the a-ferrule, b-ferrule and L-shaped hook are all made of steel.
[0011] Furthermore, the magnetic rubber strip is embedded in a side surface of the support arm, and the magnetic rubber strip is glued and fixed to the support arm.
[0012] Compared with the prior art, the utility model has the following beneficial effects: through the components consisting of the photovoltaic grid-connected cabinet body, the support arm, the magnetic rubber strip, the neutral line fool-proofing component and the live line fool-proofing component, a set of neutral line and live line fool-proofing mechanisms are provided for the photovoltaic grid-connected cabinet wiring assembly, which can help the line assembler to pre-position the neutral line and live line to be assembled on the air-open circuit breaker in advance, so that the neutral line and live line will not be installed reversely or the line will be disordered during the assembly of the copper nose of the wire to the circuit breaker. The neutral line and live line of the parallel assembly are supported by clamping, and then the neutral line anti-foolproofing components and the live line anti-foolproofing components are moved on the support arm to just above the circuit breaker where the wiring is required. This can effectively ensure the orderliness of the line layout before wiring, so that workers can quickly take the lines required for connection and assembly at that position during wiring, achieve anti-foolproofing effect, and solve the problem of the existing photovoltaic grid-connected cabinets having no anti-foolproofing positioning mechanism for the connecting lines during wiring operations, resulting in complex early lines, which can easily lead to increased risks of line assembly errors and reverse connection, affecting the stability of the use of photovoltaic grid-connected cabinets.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] like Figure 1-3As shown, a photovoltaic grid-connected cabinet with an anti-foolproof wiring mechanism includes a photovoltaic grid-connected cabinet body 1, a support arm 2 and a magnetic rubber strip 3, and also includes a neutral line anti-foolproof component 4 and a live line anti-foolproof component 5. The support arm 2 is arranged in the photovoltaic grid-connected cabinet body 1, and both ends of the support arm 2 are fixedly installed with the photovoltaic grid-connected cabinet body 1 by bolts. A plurality of neutral line anti-foolproof components 4 and live line anti-foolproof components 5 are provided, and the neutral line anti-foolproof components 4 and live line anti-foolproof components 5 are sequentially clamped along the support arm 2.
[0019] Wherein, the neutral line fool-proofing component 4 and the live line fool-proofing component 5 both include an a clamping sleeve 401 , a b clamping sleeve 402 , a spring hinge 403 and an L-shaped hook 404 .
[0020] The L-shaped hook 404 is integrally arranged on the back of the a sleeve 401 , and the a sleeve 401 is rotatably connected to one end of the b sleeve 402 via a spring hinge 403 .
[0021] Wherein, the a-cage 401, b-cage 402 and L-shaped hook 404 are all made of steel.
[0022] The magnetic rubber strip 3 is embedded in a surface of one side of the support arm 2 , and the magnetic rubber strip 3 is glued and fixed to the support arm 2 .
[0023] It should be noted that the utility model is a photovoltaic grid-connected cabinet with a fool-proof wiring mechanism. When working, the photovoltaic power worker fixes the support arm 2 to the top or bottom of the wiring air-open circuit breaker in the photovoltaic grid-connected cabinet, and arranges the neutral wire and the live wire that need to be connected to the air-open circuit breaker in sequence to the bottom or top of the corresponding circuit breaker. During the arrangement, the line is supported by the clamping between the a clamping sleeve 401 and the b clamping sleeve 402 on the neutral wire fool-proof component 4 and the live wire fool-proof component 5, so that the copper nose is clamped on the a clamping sleeve 401 and the b clamping sleeve 402. The L-shaped hook 404 on the back of the a-cage 401 is hung on the support arm 2, and is magnetically connected to the support arm 2 on the magnetic rubber strip 3 by the L-shaped hook 404, so that the a-cage 401 can be magnetically positioned at the position set by the worker. During wiring, the photovoltaic power worker can directly take the wires directly above or below the circuit breaker to connect the circuit breaker. During the wiring process, there will be no more messy lines and each wiring needs to be re-arranged. This helps photovoltaic power workers to greatly improve the accuracy and efficiency of wiring operations on photovoltaic grid-connected cabinets and achieve a fool-proof effect.
