Description
Technical Field
The utility model relates to a distribution equipment technical field, especially an overhead line's fortune dimension equipment.
Background
Along with the continuous rapid growth of resident power consumption demand, the resident is to power supply reliability and practicality constantly improve, and distribution facility upgrading and optimization increase gradually, and the drawback of existing overhead line fortune dimension equipment is in urgent need of solving. The existing overhead line operation and maintenance equipment has 3 problems: the column switch body has long opening time and low reliability. FTU's outer container protection level is low, and long-time operation leaks, and equipment damages. Night patrol, and patrol personnel cannot distinguish the on-off position of the switch in a short time due to light.
Disclosure of Invention
To the problem that exists among the prior art, the utility model provides an improve the power consumption reliability, not fragile, patrol personnel can distinguish the overhead line's of deciliter position of switch fortune dimension equipment in the short time.
The purpose of the utility model is realized through the following technical scheme.
The operation and maintenance equipment for the overhead line comprises an on-column switch body, a connection cable and an FTU (fiber to the Unit), wherein the on-column switch body comprises an insulating pull rod, an over travel spring, a flexible connection and a vacuum bulb, and the over travel of the over travel spring is 1.7-2.0 mm.
The FTU is located in the box body, and a sealing strip is arranged between the box body and the box door.
And an indicator light is arranged at the bottom of the FTU, and the indicator light is normally on in a switch closing state.
Compared with the prior art, the utility model has the advantages of: the utility model provides high power consumption reliability, not fragile, the tour personnel can distinguish the deciliter position of switch in the short time.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. pole top switch body 2, interconnection cable 3, FTU.
Detailed Description
The invention is described in detail below with reference to the drawings and specific examples.
As shown in figure 1, the operation and maintenance equipment for the overhead line comprises a pole-mounted switch body, a communication cable and an FTU (fiber to the Unit), wherein the pole-mounted switch is single-phase and comprises an insulating pull rod, an over travel spring, a flexible connection and a vacuum bulb. The overtravel of the overtravel spring is generally 2.5-3.0mm, and the overtravel of the overtravel spring is adjusted to 1.7-2.0mm, so that the sensitivity of brake separation can be improved, the brake separation time can be shortened, and faults can be effectively and quickly isolated.
The outer box protection grade of the FTU is generally IP55, and the FTU runs for a long time, and is immersed by rainwater to damage equipment. By enhancing the sealing performance of the sealing strip, the protection grade of the outer box is improved to IP65, and the problem can be solved.
The operation and maintenance equipment of overhead line is generally installed on the pole, and some special areas, equipment fixing's than higher, the circuit is tourd night, brings inconvenience for the personnel of touring, can not distinguish the divide-shut brake position of equipment in the very first time. The normally closed point of the auxiliary switch can be taken by additionally arranging a red indicator light at the bottom of the FTU, and the red indicator light is provided with DC24V voltage in the closed state of the switch. Under the switch on state, the red indicator light is on, and night patrol personnel can distinguish the on-off position of the switch conveniently.
Claims (3)
