Abstract
The utility model discloses a lower layer voltage handcart of a centrally-installed cabinet, comprising a vehicle frame, a base plate, a voltage transformer, a high voltage fuse, a lightning arrester and an insulation contact arm. The vehicle frame is arranged above the base plate and is provided with the voltage transformer. The top of the vehicle frame is provided with the insulation contact arm. One end of the high voltage fuse is connected with the insulation contact arm, and the other end of the high voltage fuse is connected with the voltage transformer. The lightning arrester is arranged between the insulation contact arm and the voltage transformer. The lower layer voltage handcart of the centrally-installed cabinet is characterized by low cost and small size.
Description
Technical field
The utility model relates to the technical field of power distribution cabinet, particularly relates to a kind of middle-placed switch cabinet lower floor voltage handcart.
Background technology
Middle-placed switch 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 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 circuit breaker; be the core of controller switching equipment, load power source is played control and protective effect.
Now market middle-placed switch cabinet lower floor voltage handcart commonly used mostly is the integral type voltage handcart that professional instrument transformer producer produces, its price is higher, cause client cost to increase, another kind is each complete manufacturer production, its volume is larger, propulsive mechanism is dumb, makes troubles for the design of cabinet and transportation installation.
The utility model content
The problem that, volume high for middle-placed switch cabinet voltage hand cost of the prior art is large, transportation is inconvenient, the utility model provide that a kind of cost is lower, the middle-placed switch cabinet lower floor voltage handcart of small volume.
For solving the prior art problem, the technical solution adopted in the utility model is: a kind of middle-placed switch cabinet lower floor voltage handcart, comprise vehicle frame, chassis, voltage transformer, high-tension fuse, lightning arrester and insulation contact arm, described vehicle frame is arranged at the top on chassis, on the described vehicle frame voltage transformer is installed, the top of described vehicle frame is provided with the insulation contact arm, described high-tension fuse one end connects the insulation contact arm, the other end of described high-tension fuse connects voltage transformer, and described lightning arrester is arranged between insulation contact arm and the voltage transformer.
Further, be connected with collets, aluminium bar and contact in turn on the described insulation contact arm.
Further, described lightning arrester is axially perpendicular to high-tension fuse.
The beneficial effects of the utility model are: the insulation contact arm adopts self-control aluminium bar contact arm, and intensity is high, and cost is low; High-tension fuse and lightning arrester adopt the at right angle setting method, and be easy for installation, and reduce volume.

Fig. 2 is Facad structure schematic diagram of the present utility model.
Embodiment
For the technical solution of the utility model and beneficial effect can more clearly be showed, below in conjunction with accompanying drawing 1-2, the utility model is described in further detail.
The disclosed a kind of middle-placed switch cabinet of the utility model lower floor voltage handcart, comprise vehicle frame 10, chassis 20, voltage transformer 30, high-tension fuse 50, lightning arrester 40 and insulation contact arm 60, described vehicle frame 10 is arranged at the top on chassis 20, on the described vehicle frame 10 voltage transformer 30 is installed, the top of described vehicle frame 10 is provided with insulation contact arm 60, described high-tension fuse 50 1 ends connect insulation contact arm 60, the other end of described high-tension fuse 50 connects voltage transformer 30, described lightning arrester 40 is set in parallel between insulation contact arm 60 and the voltage transformer 30, and the one end is connected with insulation contact arm 60.
Be connected with collets 61, aluminium bar 62 and contact 63 on the described insulation contact arm 60 in turn.
Described lightning arrester 40 is axially perpendicular to high-tension fuse 50.
20 fronts are provided with the operating grip (not shown) on the chassis, chassis 20 is provided with propulsive mechanism, insulation contact arm 60 ends are provided with contact 63, contact 63 adopts VS1 switch standard Mume flower contact, fixed contact coupling in the cabinet of the shape of contact 63, position and middle-placed switch cabinet, reliable with contacting of fixed contact, highly versatile.
The course of work and the principle of above-described embodiment are as follows:
As shown in Figure 1; middle-placed switch cabinet lower floor voltage handcart enters the service position; the contact 63 of middle-placed switch cabinet lower floor voltage handcart enters contact box in the cabinet; match with fixed contact in the cabinet; can satisfy the measurement to the middle-placed switch cabinet busbar voltage, realize the function of the electric aspects such as relaying protection, and processing be simple; easy to assembly, flexible operation is reliable.
Middle-placed switch cabinet lower floor voltage handcart disposes protection high-tension fuse 50, and this fuse is installed between insulation contact arm 60 and the voltage transformer 30, can effectively play the effect to voltage transformer 30 filtrations and short-circuit protection.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
