Description

technical field

[0001] The invention belongs to the technical field of motor starting control, in particular to a motor starting control system. Background technique

[0002] An oil field is a complex object, one of its important characteristics is time-varying. During the production process, the formation energy is constantly attenuated. The conventional way to maintain the formation energy balance is to output oil wells. The level of oil delivery pressure is an important parameter to determine the rational development of the surface pipeline and related equipment in the oil field. Especially in the later stage of development, the number of oil delivery wells, the design of the oil delivery process and the configuration of electromechanical equipment are relatively generous, and the geological conditions change greatly, which often causes The oil delivery pressure fluctuates, and the oil delivery volume is uneven and unstable. Improper control of the output pressure will b...

Embodiment Construction

[0015] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0016] A motor starting control system, including at least one main circuit and a control circuit for connecting with a corresponding motor, the control circuit includes a remote control branch, and a control switch and a first contactor coil are arranged in series on the remote control branch. The normally open contacts of a contactor are connected in series in the main circuit, and the control switch is turned on when the set condition is reached, so as to realize the conduction of the main circuit. Wherein, the setting condition is a low oil pressure signal, that is, the control switch is turned on when the oil pressure is low.

[0017] The two ends of the control switch of this embodiment are connected in parallel with a start button, and the two ends of the start button are connected in parallel with the normally open contacts of the first co...
