Abstract
The invention relates to a secondary plug for the testing of a circuit breaker handcart, which comprises a cable. One end of the cable is connected with a power supply plug and the other end of the cable is connected with a power supply female contact; and the cable is connected with a rectifier. The secondary plug has the advantages that the power supply female contact in the secondary plug is connected with a male contact of the circuit breaker handcart; after a 220V alternate current is converted into a 240V direct current by the rectifier, a power supply is provided for the circuit breaker handcart, so that control on the circuit breaker handcart is implemented and the circuit breaker handcart does not need to be pushed into a cabinet or be turned to be operated, thus, time is greatly saved and working efficiency is improved; and the secondary plug has a simple structure and is convenient to use.
Description
Technical field
The present invention relates to a kind of aid that inspection, testing equipment are used in power equipment, relate in particular to a kind of circuit breaker cart test secondary plug.
Background technology
Along with the continuous development of electric power network technique, the range of application of switch cubicle is more and more wider, and circuit breaker cart is as an important component part of switch cubicle, and its effect is also more and more outstanding with the status.When circuit breaker cart has arrived the set test period, at the trial, need draw back switch earlier, power supply is disconnected, subsequently handcart is shaken to the experiment position, shift handcart onto inspection platform then.Switch cubicle has been realized the obvious cut-off point with power supply like this, but the testing requirements switch that we need do is in and closes the position, aviation plug in this action need switch cubicle provides power supply for car switch, the aviation plug line is shorter, thereby all is dolly to be pushed into testing position again insert aviation plug in the past.Circuit breaker cart is relatively heavier, and according to the regulation of " State Grid Corporation of China's safety regulations ", circuit breaker cart retreats to testing position and must be operated by the operations staff, and too much operating breaker handcart will be wasted a large amount of time, reduces our work efficiency and can not guarantee safety.
Summary of the invention
The purpose of this invention is to provide circuit breaker cart test secondary plug a kind of simple in structure, easy to use.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of circuit breaker cart test secondary plug, comprising cable, its characteristics are: an end is connected with attaching plug on the described cable, and the other end is connected with the power supply female.
According to above-mentioned circuit breaker cart test secondary plug, its characteristics are: be connected with rectifier on the described cable.
Advantage of the present invention is: the power supply female among the present invention links to each other with the circuit breaker cart male, rectifier is converted to the 220V alternating current behind the 240V direct current and provides power supply for circuit breaker cart, thereby realize the control to circuit breaker cart, do not need again circuit breaker cart to be pushed cabinet or turn the circuit breaker cart direction and operate again, saved the plenty of time, improved work efficiency, and simple in structure, easy to use.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the synoptic diagram of installing and using of the present invention.
In the accompanying drawing: 1, power supply female; 2, cable; 3, rectifier; 4, attaching plug; 5, wall; 6, wall socket; 7, switch male; 8, circuit breaker cart Aviation cable; 9, circuit breaker cart.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further described:
A kind of circuit breaker cart test secondary plug, as shown in Figure 1, 2, comprising cable, cable 2 is taken normal cable, and an end is connected with attaching plug on the cable, and the other end is connected with the power supply female.
In the present embodiment, be connected with rectifier on the cable, rectifier 3 is selected conventional rectifier for use, and rectifier 3 is connected with power supply female 1 by cable 2, constitutes power supply.
The circuit breaker cart operating power needs direct current, and rectifier 3 is used for the 220V alternating current is converted to direct current; Aviation cable 2 is used for carrying power supply, and power supply female 1 is used for joining with switch male 7, thereby provides power supply for car switch.
Principle of work of the present invention is: the power supply female 1 of circuit breaker cart second trial power supply links to each other with circuit breaker cart male 7, rectifier 3 is converted to the 220V alternating current behind the 240V direct current and provides power supply for circuit breaker cart, thereby realize the control to circuit breaker cart, do not need again circuit breaker cart to be pushed cabinet or turn the circuit breaker cart direction and operate again, save the plenty of time, improved work efficiency.
By development circuit breaker cart test secondary power supply, saved the circuit breaker cart test period, be reduced to present 10.5 minutes in 22.5 minutes from every, and guaranteed being perfectly safe of test in the past.
When the substation breakers wheelbarrow switch is tested, circuit breaker cart is in gate-dividing state after pulling out in the switch cubicle, and institute does experiment and requires switch closure, therefore the circuit breaker cart that needs to have pulled out pushes a part in the switch again, or with the circuit breaker cart reverses its direction, joining with the aviation plug of switch cubicle provides direct supply.By circuit breaker cart secondary power supply plug, no longer need switch cubicle to provide direct supply for circuit breaker cart, so not only saved test period, also improved the security of test.
Embodiment recited above is described preferred implementation of the present invention; be not that design of the present invention and protection domain are limited; under the prerequisite that does not break away from design concept of the present invention; common engineering technical personnel make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention.
Claims (2)
