Description

Insulating clamp for fuse type isolating switch Technical Field The utility model relates to the technical field of power maintenance and use equipment, in particular to an insulating clamp for a fuse type isolating switch. Background The fuse type isolating switch is an electrical device combining the functions of the isolating switch and the fuse, and is mainly used in a low-voltage distribution system, so that the isolating disconnection of a circuit can be realized, and overload or short-circuit protection can be provided. The core functions of the circuit include (1) circuit isolation, namely, breaking the circuit in a non-current state to form a visible breakpoint for equipment maintenance or overhaul. (2) Overload/short-circuit protection, in which, the built-in fuse link fuses when the current is overloaded or short-circuited, and cuts off the fault circuit to prevent equipment damage or fire risk. The switch diaphragm is a component inside the fuse type isolating switch, and is generally made of an insulating material and used for supporting and protecting an internal component of the fuse type isolating switch and preventing dangerous phenomena such as electric arcs and the like, and is generally installed inside a shell of the isolating switch in a plug-in mode. The middle part of the switch partition board is provided with two clamp bars which mainly act as (clamp) and two side ends of the clamp bars are provided with guard plates which mainly act as (auxiliary support). In the event of a failure of an internal component of a fuse-type disconnector (including components mounted on the switch diaphragm), it is often necessary to remove the switch diaphragm for maintenance with a clamp tool. In the prior art, a worker clamps two clamp rods of a switch partition plate through a nipper clamp and the like and takes the switch partition plate out of a shell; the operating mode is that the two clamping openings of the nipper pliers clamp the positions of the clamp bars inwards, all clamping forces of the nipper pliers act on the positions of the clamp bars, and when the clamping forces are overlarge, the probability of clamping the positions of the clamp bars is high, and also, as the force is only exerted on the positions of the clamp bars of the switch partition boards on the inner sides of the clamping openings, the clamping forces acting on the positions of the clamp bars of the switch partition boards are relatively limited, and the inner side surfaces of the clamp bars are smooth, and the probability of slipping of the clamping tools and the positions of the clamp bars is high (one of two protection boards is not balanced due to the force, the switch partition boards are not easy to clamp firmly to exert the force, the probability of clamping the damaged protection boards is high, and the switch partition boards are not convenient to vertically pull out of the switch partition boards, so that inconvenience is brought to workers, and the working efficiency is correspondingly unfavorable. In summary, it would be desirable to provide a clamp that effectively clamps a switch diaphragm. Disclosure of utility model In order to overcome the defects that the switch partition board of the conventional fuse type isolating switch is not provided with a suitable picking and placing tool, the adoption of the nipper pliers brings inconvenience to workers, is unfavorable for improving the working efficiency and the like, under the combined action of related structures, the utility model provides the insulating clamp for the fuse type isolating switch, which can apply balanced clamping acting force to two guard boards of the switch partition board through the inner clamp head and the outer limiting plate, vertically separate the switch partition board from a shell of the fuse type isolating switch, reduce the probability of clamping the broken guard boards, clamp rods and slipping, bring convenience to the workers and correspondingly improve the working efficiency. The technical scheme adopted for solving the technical problems is as follows: the insulating clamp for the fuse type isolating switch comprises an outer limiting plate and an inner clamp head, wherein the lower end of the limiting plate is of an open structure, the upper end of the limiting plate is provided with a shaft hole, the inner clamp head is provided with at least two clamp heads which are respectively a left clamp head and a right clamp head, the left clamp head and the right clamp head are respectively provided with a handle and a clamp opening, the lower end of the handle and the upper end of the clamp opening are integrally formed, a connecting plate is arranged between the lower end of the handle and the upper end of the clamp opening, the connecting plates of the left clamp head and the right clamp head are installed together in a front-back overlapping mode, the upper ends of the handles of the left clamp head and the right clamp head
