Abstract
The utility model discloses a towerless water supply pump protection device which comprises three-phase power lines connected with a water pump motor, wherein a current transformer is arranged in the three-phase power lines respectively, and the current transformer is connected with an intelligent controller by a signal transmission line. When the power supply current of the water pump motor is excessively large, a power supply is controlled by the intelligent controller to be automatically cut off, so that the water pump motor can be effectively prevented from being damaged. The towerless water supply pump protection device is simple in wiring, convenient in mounting and use and reliable in performance.
Description
Technical field
The utility model belongs to supply equipment resist technology field, particularly a kind of non-tower water supply water pump protective device.
Background technology
At present, transformer station generally uses the non-tower water supply system to guarantee the needs of industrial water.And the start and stop of its water pump lean on the water container pressure monitoring system to control automatically fully, as long as when water container inner storing water amount is lower than a threshold value, and the running that the water pump chance is not stopped.When the water source water percolating capacity was too small, foreign matters such as silt, stone got in the water pump cover easily, caused the water pump rotor stall, under the situation of power supply continued power, were easy to cause pump motor to burn out; In addition, not normal when the pump motor open-phase protection, when phase-deficient operation occurring, also can cause above-mentioned similar accident, influence the normal water supply of substation operation thus, even cause power transmission and transforming equipment stoppage in transit accident.
The utility model content
The purpose of the utility model is to provide a kind of and can prevents effectively under the overladen situation of transformer
Carry out the operation of transferring the files of artificial main transformer, guarantee the non-tower water supply water pump protective device of power transmission and distribution system safety.
The technical scheme that purpose adopted that realizes the utility model is: a kind of non-tower water supply water pump protective device; Comprise the three phase mains circuit that is connected with pump motor; In the three phase mains circuit, be respectively arranged with a current transformer, current transformer is connected with intelligent controller through signal transmssion line.
The non-tower water supply water pump protective device of the utility model through the setting of current transformer and intelligent controller, when the pump motor supply current is excessive, is broken off by intelligent controller control power supply, thereby can avoid the damage of pump motor effectively.This device wiring is simple, easy to install, dependable performance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1; The non-tower water supply water pump protective device of the utility model; Comprise the three phase mains circuit 3 that is connected with water pump 1 necessary electromotor 2; In every phase power circuit 3, be provided with a current transformer 4, be used for the on-line monitoring of each phase power circuit 3 current signal, three current transformers 4 are connected with intelligent controller 5 through signal transmssion line respectively.This device connects intelligent controller 5 in use through the gate-controlled switch of signal transmssion line in power circuit 3.In water pump 1 running, when the supply current of motor 2 was excessive, current transformer 4 was transferred to intelligent controller 5 with each phase current signal, controlled the power supplys disconnection by intelligent controller 5, thereby avoided the damage of pump motor effectively.
Claims (1)
1. a non-tower water supply water pump protective device comprises the three phase mains circuit that is connected with pump motor, it is characterized in that: in the three phase mains circuit, be respectively arranged with a current transformer, current transformer is connected with intelligent controller through signal transmssion line.
