Abstract
The utility model relates to the Buchholz relay in filling transformer non-ionizing energy loss, especially a kind of waterproof Buchholz relay.Comprise the terminal box (1) of Buchholz relay, be characterized in: on the sidewall of described terminal box (1) bottom, have at least one through hole (2), and on this through hole (2), be coated with ventilation paper thus this through hole (2) is closed.Through probationary certificate; after adopting waterproof Buchholz relay of the present utility model; effectively can prevent from being exposed to Buchholz relay terminal box place that natural environment rains causes insulation to reduce due to, the intrusion of snow, water, and then causes protection malfunction, affects the defect of the reliability of electrical network.
Description
Technical field
The utility model relates to the Buchholz relay in filling transformer non-ionizing energy loss, especially a kind of waterproof Buchholz relay.
Background technology
Oil-filled transformer in power transformer operating standard regulation 0.8MVA and above oil-filled transformer and 0.4MVA and above workshop, all should install protection; When shell internal fault produces slight gas or pasta declines, instantaneous operation is answered to signal; When producing a large amount of gas, answer action in disconnection transformer each side circuit breaker.The regulator of the oil-filled transformer of on-load pressure regulation, also should install protection.Protection is as the main protection component of its internal fault; to degradation fault all energy sensitive action under transformer turn-to-turn and layer short circuit, iron core fault, inside pipe casing fault, winding inside broken string and insulation degradation and pasta, therefore transformer protection and electric parameters protection together constitute transformer main protection.
Transformer protection is different from the protection of its electric parameters, and what electric parameters protection adopted is start to add action logic, and just enter fault distinguishing program after only having startup, reliability has very large guarantee.And protection only relies on Buchholz relay to carry out differentiating rear direct export, the reliability of Buchholz relay itself can only be relied on.Large Copacity oil is invaded when formula transformer runs and is generally all exposed in natural environment, and Buchholz relay terminal box place may cause insulation to reduce because rain, snow, water etc. invade, thus causes protection malfunction.
Utility model content
The purpose of this utility model is to provide a kind of waterproof Buchholz relay, can prevent the liquid such as rain, blood, water from invading Buchholz relay terminal box.
A kind of waterproof Buchholz relay, comprise the terminal box of Buchholz relay, its special feature is: the sidewall bottom described terminal box has at least one through hole, and on this through hole, is coated with ventilation paper thus is closed by this through hole.
Wherein through hole is for circular and its quantity is 2-12, and all via bottoms are all concordant with terminal box inner bottom part.
Paper of wherein ventilating adopts filter paper.
Through probationary certificate; after adopting waterproof Buchholz relay of the present utility model; effectively can prevent from being exposed to Buchholz relay terminal box place that natural environment rains causes insulation to reduce due to, the intrusion of snow, water, and then causes protection malfunction, affects the defect of the reliability of electrical network.And tool has the following advantages: the water that bottom a, terminal box, apopore is conducive to entering Buchholz relay is discharged smoothly, and is unlikely to make junction box corroded by rain, snow, water lamp, keep that junction box is dry, insulation is good.Bottom b, terminal box, apopore adopts ventilation paper to carry out shutoff; be conducive to the discharge of junction box humid air and water on the one hand; can the entering of foreign material such as external dust be prevented and make junction box dust stratification on the other hand, cause insulation reduce thus cause false protection.C, can varying environment be adapted to, more for southern rainwater weather, and the environment such as there was dampness in the air, moisture content in terminal box can drain by this kind of Buchholz relay; And for air oxygen detrition environment such as northwests, then can keep terminal box inner drying, totally, the insulation that can effectively prevent Buchholz relay from causing because rain, snow, water etc. invade reduces, and effectively reduces the probability of Buchholz relay malfunction.D, for the transformer put into operation, the transformation of its Buchholz relay is relatively simple, convenient, and the corresponding transformation time is short.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model provides a kind of waterproof Buchholz relay, comprises the terminal box 1 of Buchholz relay, the sidewall bottom described terminal box 1 has at least one through hole 2, and on this through hole 2, is coated with ventilation paper thus is closed by this through hole 2.Wherein through hole 2 is for circular and its quantity is 8, is evenly distributed on four sidewalls, all concordantly with terminal box 1 inner bottom part bottom all through holes 2 is convenient to draining, ventilation paper employing filter paper in addition.
Claims (3)
1. a waterproof Buchholz relay, comprise the terminal box (1) of Buchholz relay, it is characterized in that: on the sidewall of described terminal box (1) bottom, have at least one through hole (2), and on this through hole (2), be coated with ventilation paper thus this through hole (2) is closed.
2. waterproof Buchholz relay as claimed in claim 1, is characterized in that: wherein through hole (2) is for circular and its quantity is 2-12, and all through holes (2) bottom is all concordant with terminal box (1) inner bottom part.
3. waterproof Buchholz relay as claimed in claim 1 or 2, is characterized in that: paper of wherein ventilating adopts filter paper.
