Description
Technical field
The utility model belongs to the technical field of power distribution cabinet, is specifically related to a kind of mid-cabinet valve mechanism and checks handcart.
Background technology
Mid-cabinet is that a kind of circuit breaker is the controller switching equipment of handcart-type; cabinet body structure is divided into three layers; the rear, upper strata is a bus-bar room; the place ahead, upper strata is the control room; the middle level is the circuit breaker cart chamber, and lower floor is the cable vault, is in the circuit breaker cart in the breaker chamber; be the core of controller switching equipment, load power source played the usefulness of control and protection.Circuit breaker cart has two positions in cabinet, one is test position, and the circuit breaker that is in test position can be safeguarded and test; Another is the service position, and the circuit breaker that is in the service position will play control and protective effect to load power source.
Mid-cabinet is provided with fixed contact in valve mechanism and the cabinet, circuit breaker cart is then corresponding be provided with about two valve push pedal and contact of breaker, fixed contact coupling in the cabinet of the position of circuit breaker cart contact, shape and mid-cabinet wherein, about circuit breaker cart the shape of two valve push pedals, position then with the valve mechanism coupling of mid-cabinet.Circuit breaker cart is provided with vehicle frame, chassis; The chassis is provided with and can advances its propulsive mechanism that advances, and propulsive mechanism is generally the nut screw body, can rotary screw rod by handle hole, and nut is moved forward and backward, and then drive circuit breaker and move forward and backward.The front of propulsive mechanism is provided with handle hole.
When circuit breaker cart was advanced to the service position from test position, two valve push pedals of circuit breaker acted on valve mechanism, and valve mechanism is opened automatically; When the circuit breaker propelling put in place, contact of breaker cooperated with fixed contact in the cabinet, breaker closing, and major loop is connected.But be advanced to the process of service position from test position at circuit breaker cart, if the valve mechanism Installation and Debugging of mid-cabinet are bad, collision of contact of breaker and valve plate or valve plate then may occur and open situation not in place, have a strong impact on device security and personal safety.And in the prior art, before circuit breaker cart is advanced into the service position from test position, whether the valve mechanism that can't know for sure in advance can operate as normal, thereby circuit breaker cart is being advanced into the process of service position from test position, has unpredictable hazards.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of mid-cabinet valve mechanism to check handcart, and can it can check the valve mechanism operate as normal.
Its purpose can realize by following scheme: this mid-cabinet valve mechanism checks that handcart comprises vehicle frame, chassis, and the chassis is provided with propulsive mechanism, and the front of propulsive mechanism is provided with handle hole; The vehicle frame both sides are separately installed with right valve push pedal and left valve push pedal, the valve mechanism coupling of the shape of two valve push pedals, position and mid-cabinet; The front of vehicle frame is equipped with toughened glass; Vehicle frame also is equipped with the insulation contact arm, and insulation contact arm end is provided with the insulation contact block, fixed contact coupling in the cabinet of shape, position and the mid-cabinet of insulation contact block.
In the toughened glass front illuminating lamp is installed, illuminating lamp is connected with luminous lamp switch and battery.
Be provided with operating grip in the front, chassis.
The vehicle frame both sides are provided with left side shrouding and right side shrouding.
The utlity model has following advantage and effect:
1, checks that the handcart and the valve mechanism of mid-cabinet mate, mean that the shaped position of the shaped position of the two valve push pedals of checking handcart and circuit breaker cart is identical; Fixed contact coupling in the shaped position of checking handcart insulation contact block and the cabinet of mid-cabinet means and checks that the insulate shaped position of the shaped position of contact block and circuit breaker cart contact of handcart is identical.In a word, the utility model checks that handcart profile, fit dimension and circuit breaker cart are identical, and check that the handcart contact block is an insulating material, therefore before the mid-cabinet of formal propelling service position, can utilize and check that handcart replaces circuit breaker cart to test circuit breaker cart.Because the rear end face of vehicle frame is equipped with toughened glass, in the toughened glass front illuminating lamp is installed, the inspection personnel can see through toughened glass and clearly observe the situation of opening that advances valve mechanism in the overall process cabinet outside cabinet, so that check the valve mechanism of mid-cabinet can operate as normal, check whether valve mechanism has catching phenomenon, to guarantee that it flexibly, reliably.
2, simple in structure, the reliability height, and also easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model at a kind of specific embodiment.
Fig. 2 is the right view of specific embodiment shown in Figure 1.
Fig. 3 is the left view of specific embodiment shown in Figure 1.
Embodiment
Fig. 1, Fig. 2, valve mechanism shown in Figure 3 check that handcart is fit to be applied to mid-cabinet, and this mid-cabinet is provided with the circuit breaker cart with its coupling, and checks that the profile and the circuit breaker cart of handcart are identical.Valve mechanism checks that handcart comprises vehicle frame 5, chassis 1, and the vehicle frame both sides are provided with left side shrouding 6, right side shrouding 4; Chassis 1 is provided with propulsive mechanism, and this propulsive mechanism is the nut screw body, and the front of screw mandrel is provided with handle hole 12; Vehicle frame 5 both sides are separately installed with the valve mechanism coupling of shape, position and the mid-cabinet of right valve push pedal 2 and left valve push pedal 7, two valve push pedals; The front of vehicle frame 5 is equipped with toughened glass 10; Vehicle frame 5 also is equipped with insulation contact arm 8, and insulation contact arm 8 adopts the epoxy resin insulating material to make, and insulation contact arm 8 ends are provided with insulation contact block 81, fixed contact coupling in the cabinet of shape, position and the mid-cabinet of insulation contact block 81.In toughened glass 10 fronts LED illuminating lamp 3 is installed, LED illuminating lamp 3 adopts battery 13 power supplies of DC power supply, and LED illuminating lamp 3 is connected with luminous lamp switch 14.Be provided with operating grip 11 in the front, chassis, below the chassis, be provided with ground connection copper bar 9.
The course of work and the principle of the foregoing description are as follows:
After checking that handcart enters the locking of cabinet test position, press luminous lamp switch 14, LED illuminating lamp 3 lights; Then operating rocker handle is inserted handle hole 12, clockwise rotate operating rocker handle, propulsive mechanism will check that handcart slowly enters the service position.In this process, right valve push pedal 2 and left valve push pedal 7 on the inspection handcart are slowly opened valve mechanism in the cabinet, the inspection personnel can see through the situation of opening that toughened glass 10 is observed valve in the cabinet outside cabinet: if check that handcart enters the service position smoothly, the insulation contact block 81 of insulation contact arm 8 ends enters contact box in the cabinet, valve plate is opened and is put in place, then check result is qualified, and valve mechanism energy operate as normal is described; Otherwise if abnormal conditions such as valve plate and insulation contact arm bump against, valve plate is opened not in place, valve plate inclination, then check result is defective, and the valve mechanism cisco unity malfunction is described.
