Abstract
The utility model provides a water prevention pressure releasing valve of the transformer, the technology problem aiming to solved is that the pressure protection device of the oiled transformer is adopted a pressure releasing valve, the defect of which is that the entering of the harmful substantial such as rainfall, humid air, and dust etc. can not be avoided for the pneumatic switch and the line leading device, and the miss alarming or refused alarming will be caused. The key point of which is that the water dust prevention micro switch arranged with a valve base with sealing circle, a membranous disc, a spring, a valve cover, a compression spring gasket, and a sign rod is arranged in the valve cover of the pressure releasing valve, and the dust and water prevention electrical connector is arranged on the valve cover. The application of the utility model is used for the oiled transformer.
Description
Technical field
The utility model belongs to the parts or the assembly of oil-filled electric transformer--transformer waterproof type pressure relief valve, and it is installed on the fuel tank case lid or sidewall of transformer, when tank pressure surpasses specified value, a kind of device that transformer is shielded.
Background technique
At present; what the pressure protective device of oil immersed transformer adopted is a kind of pressure relief valve; its objective is: when making the oil tank for oil immersion type transformer internal pressure surpass safety limit because of failure and other reasons; for the protection oil tank of transformer is not damaged; its internal pressure is discharged, send warning or trip signal by touching sensitive switch to the control room simultaneously.The structure of pressure relief valve is: valve seat, membranous disc, spring, valve bonnet and spring pressing nut, pad, valve gap and sensitive switch etc. that seal ring is housed.Its deficiency is: this electric microswitch and Outgoing Line Unit can not be avoided entering of harmful matters such as rainwater, humid air, dust fully, may cause false alarm thus or refuse to submit alert problem.
Summary of the invention
The purpose of this utility model is to provide a kind of transformer waterproof type pressure relief valve that can avoid above-mentioned deficiency.
The purpose of this utility model is achieved in that valve seat, membranous disc, spring, valve bonnet and stage clip pad, the marker post that seal ring is housed, it is characterized in that: dustproof, waterproof type sensitive switch is installed in the valve bonnet of pressure relief valve, and dustproof, waterproof type electric coupler is installed on the valve bonnet.The marker post of pressure relief valve takeoffs when valve events, and the contact of bump sensitive switch makes sensitive switch send electrical signal, is connected the warning function of realization electric signal with outside line by connecting lead and dustproof, waterproof type electric coupler.
The utility model is compared the good effect that has with the prior art scheme: sensitive switch and electric coupler all adopt security level to reach the element of IP67, stop the false alarm that harmful matters such as air, rainwater, dust through moisture cause or refused to submit the police, guaranteed the safe operation of transformer.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the pressure relief valve of another kind of mode of structure.
Embodiment
Referring to Fig. 1, will prevent dust, waterproof type sensitive switch 1 is installed in the valve bonnet 2, is connected the formation electric path by lead with dustproof, the waterproof type electric coupler 4 that are installed in the valve bonnet outer wall then.The user can be connected to the control room by the elastic cable paper and the other end dustproof, the waterproof type electric coupler and be connected realization warning and trip avoidance function with corresponding alarm signal.
The effect of this device can realize its pressure relief valve all under water, and its electrical properties is not affected, and can not occur the phenomenon of short circuit or false alarm occurring owing to element makes moist.
Referring to Fig. 2, it is the pressure relief valve of another kind of mode of structure.Same as above, on the stage clip pad 3 in the valve bonnet 2 dustproof, that waterproof type sensitive switch 1 is installed in pressure relief valve, be connected with dustproof, the waterproof type electric coupler 4 that are installed in the valve bonnet outer wall by lead then, constitute electric path.The user can be connected to the control room by the elastic cable paper and the other end dustproof, the waterproof type electric coupler and be connected realization warning and trip avoidance function with corresponding alarm signal.
Claims (2)
1, a kind of transformer waterproof type pressure relief valve, valve seat, membranous disc, spring, valve bonnet and stage clip pad, the marker post of seal ring are housed, it is characterized in that: dustproof, waterproof type sensitive switch is installed in the valve bonnet of pressure relief valve, and dustproof, waterproof type electric coupler is installed on the valve bonnet.
2, according to the described transformer of claim 1 waterproof type pressure relief valve, it is characterized in that: on the stage clip pad in the valve bonnet dustproof, that the waterproof type sensitive switch is installed in pressure relief valve.
