Since that time it has been an important protection and monitoring device for liquid-cooled transformers and choke coils. It is known for its easy operation, high reliability, maintenance-free operation and extremely long life. The Buchholz relay is built in the cooling cycle of the appliances to be protected and responds in the event of troubles like gas accumulation, loss as well as high flow of the insulation liquid. For transformers with hermetical closure by means of a membrane (rubber sack) in the expansion tank Buchholz relays can be used also as indicating device (Air Cell Failure Relay) of this membrane. The company has had for more than 50 years experience in producing Buchholz relays and other protection devices for liquid-cooled appliances. It ranks among the most distinguished manufacturers of this kind of equipment. Experiences collected and profound know-how are the sound basis for a high product quality. References from reputed transformer manufacturers and further users are proof of the high level of the products.The company is ISO 9001/2000 certified.

The staff of highly qualified engineers and experienced skilled workers do their best to guarantee top quality high-precision products. The mechanical working of the casings is done on modern CNC-controlled machine tools. The final tests, where all the functions of the Buchholz relays are checked, are done with each device by using special test equipment. Each device is delivered with a test certificate. The type diversity of the Buchholz relays is tailored to norms and standards as well as to special customer demands. EMB-Buchholz relays are in compliance with EN 50216. The type of relay to be used depends on nominal rating and construction features of appliance to be protected. Our range of products permits optimum adaptation to actual requirements. Buchholz relays may be used in open-air or also in indoor equipment. 1 VEB = nationally owned firm Elektromotoren undGertebau Barleben GmbH 4 1. Design features Casing (Figures 1A and 1B) The casing is a weather-resistant casting of light alloy and is provided with a paint coat. It is supplied either with screwed or flanged ends (1). The variants of casings are shown under para. 4, further are possible on request. The casing has sightglasses (2) for inspection of function of the switching systems. The sightglasses with scale divisions permit reading of collected gas volume. The relays can be equipped with lids (3, may be folded up) before the sightglasses. Figure 1A: casing withflange connection

Figure 1B: casing withthread connection Figure 2: cover with dismantled cap Cover (Figure 2) The cover is a weather-resistant casting of light alloy and is provided with a paint coat. Terminal box (1), test valve (2) and test key, covered by a cap nut (3) as well as a plate for operation of the test key (4) are arranged above the cover. The terminal box has an earthing contact (5) and at most eight electrical connectors (6). By the number of these connectors the design of the switching systems concerning kind and quantity of the magnet contact tubes is determined. The aluminium cap (7) seals the terminal box. If the cap is opened the contact setting (8) can be seen. The cable may be optionally brought in through one of both cable glands (9). 31 212 3567899 4 5 Switchgear (Figures 3A and 3B) The switchgear has the following main components: -Switching system -Carrier, frame-Mechanical testing device. Whereas the single-float Buchholz relay has only one switching system, the double-float Buchholz relay has an upper and a lower switching system. Permanent magnet and float are rigidly linked forming an unit that is movably fitted to the frame together with mechanical testing device and magnet contact tube(s).

Function In the following the operation of a Buchholz relay is explained using the example of a double-float Buchholz relay. The relay is built in the connecting pipe between the transformer tank and the conservator. During normal operation it is filled completely with insulating liquid. Due to buoyancy the floats are at their top position. If a fault occurs inside the transformer, the Buchholz relay responds as follows: Gas accumulation (Figure 4) Fault: Free gas is available in the insulating liquid. Response: The gas in the liquid moves upwards, accumulates in the Buchholz relay and displaces the insulating liquid level. The moving float actuates a switch contact (magnet contact tube). An alarm signal is tripped.The lower float is not affected as from a certain gas volume the gas flows through a piping to the conservator. GasOilFigure 4: Gas accumulation Insulating liquid loss (Figure 5) Fault: Insulating liquid loss due to leakage. Response: As the liquid level falls the top float moves downward. An alarm is tripped. If the liquid loss continues, conservator and piping as well as the Buchholz relay will be emptied. As the liquid level falls, the lower float moves downward. The moving float actuates a switch contact so that the transformer is disconnected. AirOilFigure 5: Insulating liquid loss Insulating liquid flow (Figure 6) Fault:Aspontaneousincidentgeneratesa pressurewavemovinginthedirectionofthe conservator. Response:Theliquidflowreachesadamper arrangedintheliquidflow.Iftheflowrate exceeds the operating threshold of the damper, thelattermovesinflowdirection.Duetothis movementaswitchcontactisactuatedsothat the transformer is disconnected. OilFigure 6: Insulating liquid flow The upper and lower switching system form a functional unit in the single-float Buchholz relay. In case of a fault, the single-float Buchholz relay normally isolates the transformer immediately from the mains system. 7 3. Tests To each Buchholz relay a works-number is given mentioned in the test certificate. Furthermore the tests made with each Buchholz relay are documented in the test certificate. -Dielectric strength test (AC 2000 V against casing) -Leakage test (25 min with 80o C warm Transformer oil at 0.25 MPa) -Functional test (damper setting, switching systems)

With each device we deliverin the agreed language: -operating instructions -test certificate. Flow test Functional and leakage test The Buchholz relays are delivered in transport cardboards. In the cap nut of the test key there is a temporary lock for the switching system. This temporary lock has to be removed before the device is taken into operation.
