Above given is the symbol for double spark gap. This type of spark gap has two small gaps between the conductors which creates double spark. It is used in spark plug for fuel ignition and as switching devices for pulse power application like discharging the capacitor at high voltage/current. The gas ionizes when the voltage exceeds the gas breaking point & it creates a spark. It is made of two conductors with small gap in between which is filled with gas. These are some of the symbols used for spark gap. The lightning arrestor diverts the surges from lightning to the earth. It is a device used for protection against lightning or high surge currents in line. It is the symbol used for lightning arrester. It provides a visual confirmation of an open circuit & a necessary precaution during maintenance. It has slightly less current capacity then circuit breakers. Isolator Circuit breaker is used for isolating the load from the source completely. It connects three phases & whenever there is an overload or short circuit in any phase, the circuit breaker trips all three phases simultaneously. Such kind of breakers is used in three phase systems in industries. This symbol represents circuit breaker with three poles. When a short circuit or an overload occurs in any of the two hot lines, the circuit breaker trips both the lines. Such type of circuit breakers has two separate hot wires going through it. This one represents a circuit breaker with two poles. It has only one Hot wire & when there is any overload or short circuit it trips. This symbol represents a single pole circuit breaker. This symbol represents a threaded circuit breaker. Its function is to break the connection when it detects any reverse flow of current to prevent any loss. Above given is the symbol of thermal switchĪ Network protector is used between the secondary terminal of the distribution transformer & the load network. It opens the circuit when the temperature increases above its rating & closes when the temperature drops from certain point. It controls the flow of current depending on the temperature. Such type of circuit breakers is used where continuous power is necessary even during maintenance.Ī thermal switch operates on the temperature. base which is fixed & the sliding breaker which can be removed without interrupting the power flow. This type of breaker is fixed & during maintenance, the power flow through the breaker needs to be stopped.ĭraw out circuit breaker has two parts i.e. The pin pulls out when the fuse blow.įixed Mounted Breakers or Non draw out circuit breaker is represented by the symbol given above. It has a striker pin that works as an indicator for showing the fuse condition. Such type of fuse is also known as striker fuse. Motors require huge current upon starting, a slow blow fuse can withstand this current without blowing. it will blow out after a short period of time when the current exceeds the maximum limit. On the contrary to fast blow fuse, the Slow blow fuse can tolerate high current for a short period of time. It is the most common type of fuse used in electrical equipment which are sensitive to high current. Fast blow fuse instantly blow when the current exceeds beyond its maximum limit. The symbolic representation of a fast blow fuses in any electrical circuit. It operates like a resistor that limits the current flow & if exceeds its certain limit then it blow out opening the circuit. These both symbols represent a protection resistor. It can switch the device manually and also provide the protection against overcurrent by breaking the circuit. Self Heating Backpacking Meals, ͜͡ | fliptext - ʇxəʇdıๅɟ.It is the symbol for fuse switch disconnector.
