Abstract
The utility model discloses an insulating baffle of box-type substation low pressure side switch, insulating baffle is the L type, and the wide face of insulating baffle is used for human and electrified cable insulation to keep apart, and the insulating baffle leptoprosopy is used for electrified circuit breaker and cable side to keep apart, wherein, both sides all are provided with square notch about the insulating baffle leptoprosopy side, and the breach of downside and ground connection row shape cooperate the use, and the card is arranged on the ground connection, and the side card is gone up to the insulating baffle leptoprosopy side between the circuit breaker space. The utility model discloses use this insulating barrier to carry out insulation isolation with electrified low tension cable and circuit breaker, can prevent that the staff mistake from bumping live equipment, stop personal equipment occurence of failure, improve the operating efficiency.
Description
Technical Field
The invention relates to the technical field of box-type substation structures, in particular to an insulating baffle of a low-voltage side switch of a box-type substation.
Background
When 0.4 kV live working is carried out on the low-voltage side of the box-type substation, accidents that operators touch live low-voltage cables and circuit breakers by mistake easily occur, and great threats exist to personal safety of the operators.
Disclosure of Invention
Based on the aim, the invention provides a method for optimally designing the position of a wind turbine blade main beam of a wind turbine generator system.
In order to realize the aim of the invention, the invention provides an insulating baffle plate of a low-voltage side switch of a box-type substation,
insulating baffle is the L type, and insulating baffle broadside is used for human and electrified cable insulation to keep apart, and insulating baffle leptoprosopy is used for electrified circuit breaker and cable side to keep apart, wherein, both sides all are provided with square notch about insulating baffle leptoprosopy side, and the breach of downside is arranged the shape with ground connection and is cooperateed and use, and the card is arranged on ground connection, and insulating baffle leptoprosopy side upside card is between the circuit breaker space.
Wherein, the insulating baffle adopts epoxy.
Compared with the prior art, the insulating baffle has the beneficial effects that the insulating baffle is used for insulating and isolating the electrified low-voltage cable and the circuit breaker, so that the worker can be prevented from mistakenly touching the electrified equipment, the personal equipment accident is avoided, the worker is prevented from mistakenly touching the electrified equipment, the personal equipment accident is avoided, and the working efficiency is improved.

Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
As shown in fig. 1, the invention provides an insulation baffle of a low-voltage side switch of a box-type substation,
insulating baffle is the L type, and insulating baffle broadside 1 is used for human and electrified cable insulation to keep apart, and insulating baffle leptoprosopy 2 is used for electrified circuit breaker 3 and cable side to keep apart, wherein, both sides all are provided with square notch about 2 sides of insulating baffle leptoprosopy, and the breach of downside and ground connection are arranged the shape and are cooperateed and are used, block on ground connection row 4, 2 side upsides of insulating baffle leptoprosopy block between the circuit breaker space.
And the insulating baffle plates are all made of epoxy resin, so that good insulating property can be ensured.
Test conditions: the low-voltage cable lead insulation shielding tool is electrically tested, the test voltage is 5kV, the test duration is 1min, no breakdown, flashover and overheating exist, and the test is qualified.
During operation, an operator wears the high-clamp arc-proof work clothes, the upper end of the narrow face of the insulating baffle is placed between gaps of the circuit breaker, the lower end of the insulating baffle is in contact with the ground, and the wide face of the insulating baffle isolates a cable, so that the operator is isolated from an electrified body in an insulating way. The narrow surface of the baffle is tightly attached to the gap of the breaker, so that the baffle is prevented from sliding down to cause insulation failure; the lower end of the baffle plate is in contact with the ground, so that the untight shielding is avoided.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
