Abstract
The utility model discloses a soft starting water pump control cabinet which comprises circuit breakers, contactors and thermal relays, wherein the circuit breakers are arranged at the upper part of the cabinet; the contactors are arranged in the middle of the cabinet; a soft starter is connected between the circuit breaker and the contactor; and the thermal relays and motors are arranged at the lower part of the cabinet. The soft starting water pump control cabinet has the beneficial effects that firstly, the control cabinet is wide in application range, flexible in control mode, strong in anti-interference capability and stable and reliable in working; secondly, the speed of the motors of the water pump is adjusted without loss in the starting process, and the smooth acceleration from zero to a rated speed is realized; thirdly, a power grid and a pipe network are free from impact, so that the service life of the equipment is greatly prolonged; and fourthly, the starting process is constant without contact switchover, and a plurality of motors can be started alternatively.
Description
[technical field] the utility model relates to electrical control equipment, specifically a kind of soft start water pump control cabinet.
[background technique] for a long time, China's town and country water system pump motor equipment is to rely on traditional Starting mode such as the step-down of star triangle, self-coupling voltage reducing to realize the purpose that supplies water to the user.The tradition Starting mode is serious impact electrical network and pipe network not only, and damages the control apparatuss such as water pump, motor, pipe-line system, compresses their working life, is difficult to the normal demand that guarantees that enterprise produces, resident living supplies water.How changing the Starting mode of pump motor equipment, guarantee the safe operation of electrical network, pipe network, water system electric equipment, guarantee that enterprise produces, the normal supply of resident living water, is the key subjects that those skilled in the art are badly in need of solving.
[summary of the invention] the utility model provides a kind of soft start water pump control cabinet for the problems referred to above.
This soft start water pump control cabinet comprises circuit breaker, contactor and thermorelay, it is characterized in that, cabinet top is provided with circuit breaker, the cabinet middle part is provided with contactor, is connected with soft initiator between circuit breaker and the contactor, and the cabinet bottom is provided with thermorelay and motor.
The beneficial effects of the utility model are: 1, Applicable scope is extensive, and control mode is flexible, and antijamming capability is strong, and working stability is reliable; 2, lossless adjusting pump motor rotating speed in the start-up course can be realized from zero to the level and smooth acceleration between the rated speed; 3, to electrical network and pipe network without impact, working life of extension device greatly; 4, start-up course is continuous, and No-contact switch can start multiple electric motors by turns.
