Abstract
The utility model relates to the motor protection device field, in particular to a motor protection device of a diving pump. The device has the technical proposal that a transformer B and a rectifying block DZ and a capacitor C form a feed circuit; a resistor R, an audion T and a relay J form a water level automatically detecting control circuit; a normally open contact J-1 of the relay J is connected to a power loop of the diving pump in series. The utility model has simple structure and convenient installation, and is installed in the power loop of the driving pump. Under the condition that the driving pump pumps out water, the power supply of the driving pump is closed in time, thereby playing the role of protecting the security of the driving pump.
Description
Technical field
The utility model relates to the electric motor protective device field, specifically is a kind of motor for submerged pump protector.
Background technology
Water resource is in short supply at present, need exploit and quote underground water in a large number, and immersible pump is to quote phreatic common equipment.And present immersible pump protective circuit only is the protected mode by current overload, but the accident that immersible pump also can burn under anhydrous situation.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, provide a kind of can be under the anhydrous situation of immersible pump the motor for submerged pump protector of automatic disconnection power supply circuit.
Its technical scheme is: form power supply circuits by transformer B, rectifying block DZ, capacitor C; Form automatic water level by resistance R, triode T, relay J and detect control circuit; The normally opened contact J-1 of relay J is connected in the immersible pump electric power loop.
The utlity model has simple in structurely, easy for installation, be installed in the immersible pump electric power loop, immersible pump is drained under the situation of water, in time closes the immersible pump power supply, plays protection immersible pump purpose of safety.
Description of drawings
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.AN imports with power supply among the figure; DJ is an immersible pump; XY is the water level detecting probe, is installed near the immersible pump.
Embodiment
Be further described with operation principle with regard to its circuit formation below in conjunction with accompanying drawing: transformer B is connected rectifying block DZ, capacitor C is formed power supply circuits; Triode T connects resistance R, relay J is formed automatic water level and detected control circuit; Relay J two ends parallel diode D; The normally opened contact J-1 of relay J is connected in the immersible pump electric power loop.
During operate as normal, behind the energized AN, water level detecting probe XY triggers and conducting triode T forward through resistance R, relay J adhesive, the closed immersible pump operate as normal of normally opened contact J-1; When the well low water level drops to water level detecting probe XY when following, triode T will can not get trigger voltage and end, and relay J discharges, and normally opened contact J-1 disconnects, and immersible pump quits work; Protection immersible pump purpose of safety.
Claims (2)
1. a motor for submerged pump protector is characterized in that: connect to form power supply circuits by transformer (B), rectifying block (DZ), electric capacity (C); Connect to form automatic water level by resistance (R), triode (T), relay (J) and detect control circuit; The normally opened contact (J-1) of relay (J) is connected in the immersible pump electric power loop.
