Abstract
Disclosed is a motor energy-saving running device in which a gated stroke switch MK and a gated intermediate relay KJ3 are additionally arranged in an automatic bypass circuit control system. The gated stroke switch MK controls the gated intermediate relay KJ3. A mechanical contact of the gated stroke switch MK contacts with a distribution box door. A normally-opened contact of the gated intermediate relay KJ3 is connected in series with a normally-opened contact of a starting and stopping intermediate relay KJ2. A normally-closed contact of the gated intermediate relay KJ3 is connected in series with a normally-opened contact of a sensing intermediate relay KJ1. The motor energy-saving running device effectively prevents equipment damages and personnel casualties caused by accident sudden starting of a bypass circuit when a door of an electricity-saving appliance (distribution box) is opened for maintenance and measurement.
Description
Technical field:
The utility model relates to surface production facilities field, oil field, is specifically related to a kind of energy saving motor performer.
Background technology:
In the oil extraction in oil field field, power-actuated control device of electric motor breaks down, quits work when reporting to the police at electricity-saving appliance, and the sensing relay discharges, and system automatically converts under bypass condition and works.To control be all manually to control with change over switch for the auto by pass system in the past, in case operate miss will cause the work of auto by pass System Sudden, causes device damage and casualties.
The utility model content:
The utility model is intended to overcome the deficiencies in the prior art, the energy saving motor performer that a kind of result is simple, easy to use, the safety automation bypass functionality is arranged is provided, and this energy saving motor performer has effectively prevented from playing suddenly machine cause damage of equipment and casualties at maintenance, measurement, operating personnel's misoperation equipment.Can find in time that whether electricity-saving appliance is in normal operating conditions when oil recovery work routine inspection every day oil well.
The technical solution of the utility model is: this energy saving motor performer is to set up a gate travel switch MK and a gate auxiliary relay KJ3 in the auto by pass circuit control system, gate travel switch MK controls gate auxiliary relay KJ3, the mechanical contact of gate travel switch MK touches mutually with distribution box door, the normally opened contact of gate auxiliary relay KJ3 and startup, a normally opened contact that stops auxiliary relay KJ2 are connected, and the normally-closed contact of gate auxiliary relay KJ3 is connected with sensing auxiliary relay KJ1 normally opened contact.
The utlity model has following beneficial effect: the utility model is that the energy saving motor performer can the safe device that automatically is transformed into power frequency supply when breaking down.Prevent that oil pumper from causing shutdown in unattended situation, affect the generation of freezing phenomenon in oil well output and winter.The utility model increases a gate auxiliary relay in the auto by pass system of maturation, allow auto by pass thrashing when having the people to open distribution box operation maintenance.Play machine cause damage of equipment and casualties when effectively having prevented personnel's misoperation suddenly.Can find in time that whether electricity-saving appliance is in normal operating conditions when oil recovery work routine inspection every day oil well.
Description of drawings:
Accompanying drawing 1 is circuit diagram of the present utility model.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this energy saving motor performer is to set up a gate travel switch MK and a gate auxiliary relay KJ3 in the auto by pass circuit control system, gate travel switch MK controls gate auxiliary relay KJ3, the mechanical contact of gate travel switch MK touches mutually with distribution box door, the normally opened contact of gate auxiliary relay KJ3 and startup, a normally opened contact that stops auxiliary relay KJ2 are connected, and the normally-closed contact of gate auxiliary relay KJ3 is connected with sensing auxiliary relay KJ1 normally opened contact.
When distribution box at closing time gate travel switch MK connect, gate auxiliary relay KJ3 adhesive, the normally opened contact of gate auxiliary relay KJ3 is turned into closing point, for auto by pass ready.Gate auxiliary relay KJ3 with startup, stop auxiliary relay KJ2 and connect with sensing auxiliary relay KJ1, only auto by pass could start under the state that these three auxiliary relays are connected simultaneously.When distribution box door was opened, gate travel switch MK disconnected, the outage of gate auxiliary relay KJ3 pull-in winding, and the contact discharges, auto by pass thrashing.Whether normally sensing auxiliary relay KJ1 is the identification electricity-saving appliance sensing relay of operation in addition, provide direct current 12V pick-up voltage for sensing auxiliary relay KJ1 during electricity-saving appliance work, 12V loss of voltage during the electricity-saving appliance fault, sensing auxiliary relay KJ1 is normally closed closed, distribution box is at the state of closing the door, and KM1 power on adhesive auto by pass system starts working.This system has effectively prevented electricity-saving appliance (distribution box) unexpected starting cause damage of equipment and casualties suddenly of bypass circuit when the maintenance of opening the door, measurement.Whether in working order can in time find electricity-saving appliance when oil recovery work routine inspection every day oil well.
