Abstract
The utility model discloses a knob type switch electrical appliance having a tripping type indication function comprising a gear, a knob handle, and a fault indication mechanism. The knob handle is fixedly connected with a gear lock, which is disposed on a housing cover in a pivoted manner. Gears of the gear lock are engaged with teeth of the gear. The fault indication mechanism comprises a locking clamp, a spring, and a gap disposed in the gear lock. One end of the spring is connected with the housing cover by a first connecting structure, and the other end of the spring is connected with a locking clamp by a second connecting structure. One side of the gap is provided with a connected ON sliding surface, and the other side of the gap is provided with a connected OFF sliding surface. The locking clamp capable of moving linearly is disposed on the housing cover by an installation structure, and the direction A of the linear movement is respectively vertical to the two sliding surfaces, and is parallel to the direction of the elastic force of the spring. When handle is turned from the OFF position to the ON position by a user or vice verse, the locking clamp head can pass by the gap by sliding from one sliding surface to the other sliding surface. When the handle is disposed on the ON position or the OFF position, the locking clamp head is not in the gap. During the tripping caused by the faults, the locking clamp head can slide in the gap and stay in the gap.
Description
Technical field
The utility model belongs to Low Voltage Electrical Apparatus; relate to a kind of knob switch electrical equipment; for example a kind of motor protective circuit breaker with fault trip indication; particularly, in the time that device for switching breaks down, in the main body of device for switching, can provide a kind of dropout indication of distinguishing fault trip and trip free.
Background technology
Circuit breaker, starter etc. are the most frequently used low-tension switch electric appliances.Along with the raising day by day of the management expectancy of using electricity automation and safety utilization of electric power, the defencive function of low-tension switch electric appliance is more and more universal.When defencive function refers in the circuit of controlling at device for switching if there is faults such as short circuit, electric leakage, overload, overvoltage, under voltage, phase shortage, ground wire open circuits, the device for switching tripping operation of can automatically threading off, the circuit that cuts off its control.Under normal circumstances; there is the device for switching of defencive function; all there are three kinds of operating states: normal (ON) state that closes a floodgate, normal (OFF) state, fault trip (TRIPPED) state of disconnecting, the demonstration of these three kinds of operating states can intuitively realize by the position of the operating grip of device for switching.The operating grip of device for switching has knob, button, three kinds of forms of straight pull conventionally, wherein adopt the device for switching of knob operating grip to be conventionally referred to as knob switch electrical equipment, joystick knob, as hour hands, can next clear with angular displacement, intuitively, inerrably point to its current residing position.But, because its joystick knob after the operating mechanism dropout tripping operation of current device for switching is all to get back to OFF position, can not indicate TRIPPED state, maintenance personal cannot find out it is which kind of fault in the time of maintenance from body, gives and keeps in repair and will bring inconvenience.
The patent No. is that 98801334.7 Chinese invention patents disclose a kind of switchgear with switch lock, this switch lock has a switch lever, one claw and a pawl type lever as claw bearing, this ratchet rotates around its supporting axis in the time threading off, and release-push bar is to handle contact, this switchgear also has a handle being effectively connected with switch lock, one blocking mechanism is set in switch lock, this blocking mechanism is designed to have the spring arm form of a locking head, the first side of this locking has sliding surface, opposite side has locking face, it allows the claw of threading off to deviate from the time threading off, and claw is slided in the time deviating from along sliding surface, and fixed by locking face in the time of backswing, stop thus the backswing of claw, and be fixed on certain position, handle is now because it effectively connects on the centre position between open position and the on-position that is maintained at switchgear.The essence of this type of execution mode is the locking part that has designed a Plastic, and balanced controls also make mechanism rest on TRIPPED position.The defect of the prior art has three: one, because mechanism discharges a large amount of kinetic energy to energy-stored spring the process of TRIPPED position from the moment of threading off, and the target of plastics latching member is exactly the kinetic energy that absorbs this process by the distortion of self, and make by force mechanism kinematic part rest on TRIPPED position static, therefore, this locking part must bear very large impact, repeatedly after fault trip, this part easily produces fatigue fracture under alternate stress, cannot absorb energy by the distortion of self again, and cause TRIPPED disabler; The 2nd, because mechanism's impulsive force that energy-stored spring discharges claw in dropout process is very large, and in claw backswing and while being fixed on certain position, energy-stored spring is still held larger active force to claw, so the fixed position of claw changes greatly, thereby make the stop of handle between open position and on-position have drift, this drift can hinder the clear and accurate of indication TRIPPED, even can cause the erroneous judgement of maintenance personal to TRIPPED state; The 3rd, if adopt this switch lock, deliberately destroy the automatically reset advantage of the existing operating mechanism with auto-reset function, in later stage of fault trip process (the moment that approximately releases energy from energy-stored spring), latch under the elastic force effect of latch spring and automatically engage with tripping, and this engagement is not subject to the restriction of handle current location, can be directly to ON position operation in TRIPPED position, so conventional Automatic-reset operating mechanism without detaining again operation obviously has advantages of easy to operate.But, because the principle of No. 98801334.7 Chinese invention patents is exactly to utilize the locking face of locking head to stop that the backswing of claw comes lock handle position, so at TRIPPED position limitation engaging of pawl type lever and claw, thereby make operating mechanism can only become again button, this kind of switch lock can only be adapted to the operating mechanism of button again in other words, be that handle can only be to OFF position operation from TRIPPED position, can not be from TRIPPED position directly to ON position operation.
Utility model content
In order to have overcome the defect of prior art, the purpose of this utility model is to provide a kind of knob switch electrical equipment with the indication of dropout type, it adopts faulty indication mechanism and coordinates with the TRIPPED breach on gear lock in operating mechanism, effectively avoid energy-stored spring impulsive force to faulty indication mechanism in fault trip process of operating mechanism, and release moment of energy at energy-stored spring, accurately limit the rotation of gear lock, control the joystick knob being fixedly connected with gear lock and accurately rest on TRIPPED position, be convenient to maintenance personal's TRIPPED identification, making maintenance personal fundamentally can distinguish fault disconnects and still transships the non-short trouble of class and disconnect, thereby for maintenance provides convenience, not only can improve useful life and the indication reliability of faulty indication mechanism, and can be common to again two kinds of different routine operation mechanisms of button and Automatic-reset.
