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.
