the accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
embodiment:below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1, the invention provides a kind of high-potting integral intelligent switching motherboard, this switching motherboard comprises disconnecting link 1, earth leakage protector 2, often drives button 4, normally closed button 5, A.C. contactor 6 and overcurrent relay 7; Disconnecting link 1 is connected to A.C. contactor 6, and A.C. contactor 6 is connected to leading-out terminal on the one hand, is connected on the other hand overcurrent relay 7; Drive button 4 and be connected on the one hand between disconnecting link 1 and stream contactor 6, be connected to overcurrent relay 7 on the other hand with after normally closed button 5 is connected, overcurrent relay 7 is connected to leading-out terminal.
Also be connected to pilot lamp 3 between disconnecting link 1 and A.C. contactor 6.
Obtain the leading-out terminal place at this switching motherboard and also be provided with voltage table 8.
The socket used in high-potting now is traditional socket or simple single-pole switch, only has the function of simple electric energy transmitting, for personnel and equipment, without any defencive function, under the overall situation that people-oriented instantly, is obviously inappropriate.Especially for the high-tension testing crew of frequent contact, design and aly there is the safe and reliable switching motherboard of multiple protector and just seemed necessity very.High-potting had both had personnel's defencive function to personnel while getting an electric shock with the integral intelligent switching motherboard; while also having testing equipment generation excess current, to the defencive function of equipment, the realization of these two functions is to be realized by the earth leakage protector installed additional and overcurrent relay.
earth leakage protector
Earth leakage protector mainly is comprised of three parts: detecting element, middle amplifying element, operation topworks.The principle of work of earth leakage protector is that earth leakage protector is installed in the line, and primary winding is connected with the circuit of electrical network, and secondary coil is connected with the electrical apparatus release in earth leakage protector.When consumer normally moves, in circuit, electric current is equilibrium state, and in mutual inductor, the current phasor sum is zero.Owing to there is no residual current in primary winding, so can not respond to secondary coil, the switchgear of earth leakage protector moves in closure state.When device housings occurs to leak electricity and has the people to touch, in trouble spot, produce shunting, this leakage current is through human body-the earth-working earthing, return to transformer neutral point, this part electric current current transformer of not flowing through, cause in mutual inductor the electric current that flows into, flows out imbalance to occur, the current phasor sum is non-vanishing, produces residual current in primary winding.Therefore, just can respond to secondary coil, when this current value reaches the action current value of this earth leakage protector restriction, automatic switch is threaded off, and cuts off the electricity supply.
High-potting is installed at the outgoing line side of the end of incoming cables disconnecting link of switching motherboard with the earth leakage protector in the integral intelligent switching motherboard; the electric shock occurred for the charged live wire of personnel's false touch in process of the test has protective effect preferably; but to contact personnel's unprotect effect of live wire and zero line simultaneously; also unprotect effect of excess current is occurred in test in testing equipment; therefore just need to install another kind of protective device, i.e. overcurrent relay additional.
overcurrent relay
The operating principle of overcurrent relay is combined type, and it is comprised of two elements of induction type and electromagnetic type, two public coils of element.When coil passes to alternating current, in the electromagnet of sensing element, phase shift effect due to short-circuited conducting sleeve, produce two magnetic fluxs that phase place is different, this magnetic flux and its vortex interaction of responding in the aluminium dish, the generation electromagnetic force is known makes the aluminium disc spins, when electric current increases to setting current, electromagnetic torque is greater than the moment of reaction of spring, aluminum frame rotates, fan tooth and worm screw interlock, and rise along with the worm screw rotation, its push rod promotes the moving iron of electromagnetic component, when the air gap between moving iron and electromagnet is reduced to a certain degree, moving iron is by adhesive, the top board of moving iron afterbody promotes junction closure.
High-potting is arranged on the leading-out terminal of switching motherboard with the overcurrent relay in the integral intelligent switching motherboard, and in the switch control circuit of access switching motherboard.When something unexpected happened; as cause current surge in loop; surpass overcurrent relay definite value the time; the normally closed contact of overcurrent relay will disconnect; the contactor loop has also just disconnected, and contactor will dead electricity like this, and contactor is disconnected; and then make the switching motherboard outage, reach the protective effect to equipment and personnel.
integrated design
High-potting adopts integrated design with the integral intelligent switching motherboard, not only has good protective effect, has also had voltage table and pilot lamp integrated, makes the process of high-potting easier, quick and safety.Before high-potting starts, according to relevant rules requirement, need to be measured supply voltage, guarantee that supply voltage is consistent with the testing equipment required voltage, ordinary test equipment needs the voltage of 220V, and in connecing the process of power supply, wiring error likely occurs, making output voltage is line voltage, causes supply voltage too high, and burn out equipment, cause unnecessary economic loss.
High-potting has installed voltage table with the integral intelligent switching motherboard additional at leading-out terminal, needn't carry out again the work of measuring voltage before test, only need check that high-potting gets final product with the measurement numerical value of voltage table on socket, avoided carrying too much equipment simultaneously and connect and take out stitches frequently, reduced test procedure, improved test efficiency, high-potting has also installed pilot lamp additional with the integral intelligent switching motherboard, can accurately reflect the whether charged of switching motherboard, prompting personnel in use take care.Simultaneously, can also be by the coordinating of pilot lamp and voltage table, the position while confirming the switching motherboard fault.For example, can avoid when pilot lamp damages, think the not charged and situation of wiring or false touch switch electrified body repeatedly of switching motherboard by mistake.
