Abstract
The utility model relates to a control line suitable for testing and debugging the transition connection of a 10-35 kV handcart switch cabinet using a 58-pin female control plug. The control line comprises a 58-pin control line plug and a 58-jack control line female plug, wherein the control line plug is connected with the control line female plug through 58 connection lines; an insulating hose is sleeved outside the 58 connection lines; each connection line is an insulation skin soft copper wire with a cross section area of 2.5 square millimeter and a withstand voltage larger than or equal to 500V. The control line has the beneficial effects that the control line for the existing handcart switch cabinet is prolonged; and a handcart switch is prevented from moving back and forth in the pre-test annual inspection to take a test power supply, so that not only is the work efficiency improved, but also the distance between a human body and charged equipment or a dangerous source is ensured.
Description
Affiliated technical field
The utility model relates to a kind of test of the 10kV-35kV wheelbarrow switch cabinet that uses 58 pins control female, control line that the debugging transition connects of being applicable to.
Background technology
At present; In handcart switch cabinet, most handcart is installed in the concealed location of cabinet downside usually like the control line connector block of the handcart of 35kV electric pressure; Because the narrow space of cabinet downside is awkward; During handcart turnover cabinet, run into because of carelessness easily and the control line plug is taken out of outside the female, even cause the damage of pullling of control line connector block.In order to prevent that the control line plug is pulled out when the service position; Usually through being set, realizes the control line plug latching device in the prior art; But control line plug latching device of the prior art only could be realized locking when handcart closes on the service position, and between test/isolated location to service position, handcart control wire plug but is in non-blocking and can be transferred to; Can not ensure the reliable control of electrical interlock like this, have the sunken trouble of misoperation.
Summary of the invention
In order to address the above problem, the utility model provides a kind of lengthening control line of the 10kV-35kV of being applicable to wheelbarrow switch cabinet, both conveniently makes an experiment, debugs, and not influenced by the environment size, has good result of use.
The technical scheme of the utility model is: a kind of wheelbarrow switch cabinet control line; Comprise one 58 pin control line plug; And one 58 hole control line female, being connected through 58 connecting lines between said control line plug and the control line female, said 58 connecting line outsides are with flexible insulated hose.
Said connecting line is 2.5 square millimeters of areas of section, withstand voltage insulated hull annealed copper wire more than or equal to 500V.
The beneficial effect of the utility model is to have prolonged existing wheelbarrow switch cabinet control line, avoids in the prerun annual test, moving around of wheelbarrow switch to get experiment power supply, has not only improved operating efficiency, has also ensured the distance of the person with charging equipment or dangerous matter sources.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1; A kind of wheelbarrow switch cabinet control line; Comprise one 58 pin control line plug 1, and one 58 hole control line female 2, be connected through 58 connecting lines between control line plug 1 and the control line female 2; Connecting line is 2.5 square millimeters of areas of section, withstand voltage more than or equal to 500V insulated hull annealed copper wire, and flexible insulated hose 3 protections are adopted in the outside.Control line female 2 both sides are provided with alignment pin 4, and control line plug 1 correspondence position is provided with location notch, and the location notch outside is provided with buckle 5, is used for fixing alignment pin 4, and plug is connected firmly, and available in case of necessity many control lines serial connection is used.
During use; Break off accumulation power supply, operation (control) power supply earlier; Can the cabinet door be locked after pulling down panel upper observation hole glass in conjunction with inspection operation; Wheelbarrow switch, is connected control line female 2 respectively with the breaker connection box with plug 1 with existing switch cubicle control line plug from inspection hole during the position in maintenance, the accumulation power supply that closes at last, operating power etc. can be carried out work such as each item test again.
Although illustrated and described the embodiment of the utility model; For those of ordinary skill in the art; Be appreciated that under the situation of principle that does not break away from the utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, the scope of the utility model is limited accompanying claims and equivalent thereof.
